Marianne Elliott is the first woman to win two Tony awards for theatre direction: the first for War Horse and the second for The Curious Incident of the Dog in the Night Time. Both transferred to Broadway from the National Theatre, London, and have gone on to travel the world.

Marianne's parents, grandparents and great-grandparents all worked in the theatre. Her father, Michael Elliott, was a founding director of the Royal Exchange theatre in Manchester and her mother, Rosalind Knight, now in her 80s, has enjoyed a lifetime on the stage and is still working. Although Marianne read Drama at Hull University, it wasn't until she was in her late 20s that her career began, when she became assistant director at the Regents Park Open Air Theatre. She went on to follow in her father's footsteps, working at the Royal Exchange, before becoming Associate Director at the National Theatre in London. In 2017 she left to set up her own theatre company with producer Chris Harper. Their next show will be Stephen Sondheim's Company.

In addition to all her theatrical prizes, she has just been awarded the OBE for services to theatre in the 2018 Birthday Honours list. She is married to actor Nick Sidi and they have one daughter.

Baroness Newlove is the Victims' Commissioner for England and Wales. She became a campaigner after her husband, Garry Newlove, was murdered by several youths in 2007. Born in Salford in 1961 she grew up in a working class family. Having left school at sixteen she became a copy typist at a magistrate's court and later a committal court assistant. She met Garry when she was 20 and they married and had two daughters. In 1992, when he was just 32, Garry was diagnosed with stomach cancer. He survived and the couple went on to have a third daughter.

The family lived in an area of Warrington which was experiencing an increase in anti-social behaviour. In August 2007, Garry went outside to investigate a disturbance and was viciously attacked by some youths in front of his three daughters. Three days later, the decision was taken to switch off his life support. Three youths were subsequently found guilty of Garry's murder and in the wake of the family's experience, Helen set up an initiative called Newlove Warrington to provide support to the young people in the area.

She was given a peerage in 2010 and sits on the Conservative benches. She took up various roles in support of victims in the House of Lords, culminating in her appointment as Victims' Commissioner, a post she took up in 2013. She is currently in her second term and will be serving in the post until 2019.

Helen remarried in 2012.

Billie Jean King won 39 Grand Slams and a total of 20 Wimbledon titles and is regarded as one of the greatest tennis players of all time.

Born in California in 1943, she was the eldest daughter of Bill and Betty Moffitt. She discovered tennis at the age of ten: at 15 she won in her age bracket at the Southern California championships, and in 1961, she won the women’s doubles at Wimbledon with Karen Hantze, the youngest pair to achieve such a victory.

In 1968, when professional competitors were admitted to Grand Slam tournaments, she won Wimbledon for the third time and was paid just £750 while Rod Laver, the Men's champion, took home £2,000. So began her campaign for gender equality, which involved boycotting tournaments and setting up their own professional women’s circuit. In 1973, then aged 29, she beat the 55-year-old former tennis champion Bobby Riggs in a match which became known as 'The Battle of the Sexes': it remains the most-watched tennis match ever. That year the US Open awarded the same financial reward to men and women and in 2007 Wimbledon followed suit. Billie Jean also founded the Women’s Tennis Association and the Women’s Sports Foundation in the 1970s.

She married her husband, Larry, in 1965 but by the late 1960s, she had realised that she was gay. She was outed by a former lover who sued her for palimony in 1981, and although she won the case, she lost almost all her commercial endorsements. She has been with her partner, Ilana Kloss, for nearly 40 years and retired from singles matches in 1983 and doubles in 1990. She was awarded the Medal of Freedom by President Obama in 2009 and has continued to be an ambassador for her sport and for gender equality.

Philip Treacy is one of the most prolific and acclaimed hat designers working in the UK.

His work was very much in evidence at this year's Royal Wedding and at Royal Ascot. Meghan Markle wore one of his designs for her first official public engagement as the Duchess of Sussex. Other notable clients include Madonna, Tina Turner, Grace Jones, who has showcased his creations on and off stage, and Lady Gaga, for whom he made a black telephone hat.

Originally from Ahascragh, a small village in County Galway, Ireland, Philip learned to sew when he was six years old. He grew up opposite a church and he recalls how, as a young boy, he would go to all the weddings, uninvited, to look at the clothes and in particular the wedding dresses.

He went on to study fashion at the National College of Art and Design in Dublin, and then won a place on the MA fashion design course at the Royal College of Art in London, graduating in 1990 with first class honours. He enjoyed a meteoric rise to success when fashion stylist Isabella Blow saw his student hat collection. She introduced him to Karl Lagerfeld, who quickly invited him to design hats for Chanel Couture when he was still in his early twenties.

He has won the title of British Accessory Designer of the Year at the British Fashion Awards on five occasions, and was awarded an honorary OBE for services to the British fashion industry in 2007.

Guy Singh-Watson is an organic farmer and founder of Riverford, a major British supplier of organic vegetables through a box delivery scheme. Born in 1960 and the youngest of five children, his parents became tenant farmers in Devon in 1951. He describes himself as "a proper little farm boy", and spent his free time outside, clambering up trees, catching rabbits, rearing his own pig and helping on the farm.

Severely dyslexic, he disliked school, but thanks to an aptitude for performing well in exams, he won a place at Oxford University to read Agricultural and Forestry Science, graduating with a First. He briefly joined the family farm, but left to become a management consultant in London and then New York, returning to the farm in 1986. He started cultivating vegetables on three acres of land with a wheelbarrow and a borrowed tractor, and found his niche, moving from three to 18 to 50 acres quite rapidly.

Initially, Guy sold to supermarkets, but became convinced that there must be a better way of getting his produce to customers, and set up a veg box scheme in 1993. His company now delivers to around 50,000 homes a week and had a turnover of £56.7 million in 2017.

Martina Cole is a British crime writer, known to her fans as the Queen of Crime.

Martina has written 24 novels, 15 of which have topped the original fiction sales charts - more than any other author. She has sold more than 16 million books around the world, and her work has been translated into 29 languages. She also works in prisons, leading reading schemes and writing workshops for prisoners.

Martina grew up in Essex, the youngest of five children born to Irish parents. She was expelled from her convent school at 15 for reading a book by Harold Robbins. She married at 16, divorced at 17 and then had a baby at the age of 18. She wrote stories and scripts in her spare time to amuse herself, whilst taking on a series of low-paid jobs, including cleaning, waitressing, stacking shelves and leafletting.

At the age of 31, she re-discovered one of her early attempts at a novel, and decided to send it to an agent. She chose Darley Anderson from the Writers' and Artists' Yearbook because she liked the sound of the name. He quickly contacted her and told her she would be a star. He was right: she received an advance of £150,000, then a record for a first time novelist. She has written a best-selling crime novel almost every year ever since.

John Walker Motson, OBE, also known as Motty, has been commentating on football since 1971. He covered more than 2000 games on television and radio, including all the major football championships, 29 FA Cup finals (with an additional five replays), 10 World Cups, 10 European Championships and 200 England games. At the age of 72 he's just retired.

Known not only for his footballing knowledge and his voice, he is often recognised by his knee-length sheepskin coat. His passion for football was ignited by his father, a Methodist minister for 40 years, who on his one day off each week would take his only son to watch football. The first game John attended was at Charlton Athletic when he was seven, and the excitement of it inspired him to create scrapbooks of footballing facts and collect match programmes.

After five years at boarding school, where he wasn't allowed to play football, he left at 16 after one term doing A levels. He joined the Barnet Press as a trainee reporter and then moved onto the Sheffield Telegraph. When BBC Radio Sheffield, one of the first six local radio stations, came on air, he was one of the reporters pulled in to give match summaries. He then moved to the BBC as a sports assistant in radio, before joining the Match of the Day team on television.

He has been supported in his career by his solicitor wife, Annie, who meticulously kept details of every match in thick A4 books which John used for his preparation. He was awarded an OBE for services to football and in May 2018 he was honoured by BAFTA with a Special Award for his lifetime's work.

Professor Carlos Frenk is a cosmologist and one of the originators of the Cold Dark Matter theory for the formation of galaxies and the structure of the universe. He has worked at Durham University since 1985, where he was appointed the inaugural Ogden Professor of Fundamental Physics in 2001 and has been Director of the Institute for Computational Cosmology since 2002.

Born in Mexico in 1951, he is the son of a German Jewish immigrant father and a Mexican mother with Spanish roots. After completing his physics degree in Mexico, he came to Cambridge University in the mid-1970s to do a PhD in Astronomy. His first postgraduate job took him to the University of California where he worked on a computer simulation of the universe with three fellow cosmologists, disproving the idea that the universe contains hot dark matter and establishing the theory of cold dark matter instead.

Professor Frenk's papers have received more than 100,000 citations, making him one of the most frequently cited authors in the field of space science and astronomy. He has won a number of prizes for his work, including the Gold Medal of the Royal Astronomical Society. He was awarded a CBE in 2017.

Gillian Reynolds spent 42 years as the radio critic of the Daily Telegraph before she was headhunted by the Sunday Times at the age of 82. Born into a working class family in Liverpool, her mother ran a market stall and her father was a seaman, but also a gambler. Her mother was determined to ensure that Gillian had a good education, and she was the first in her family to go to a grammar school. She went on to study English at Oxford.

She took up an internship in America, where she met her husband, and they returned to Liverpool when she became pregnant with the first of her three sons. She first worked as a radio critic for the Guardian in 1967. She became the first female controller of a commercial radio station when she joined Radio City, Liverpool, in 1974. She moved to London in 1975 when she left her troubled marriage, and secured the job of radio critic for the Telegraph, as well as working as a journalist in television and radio, at one point even co-presenting the Today programme.

She chaired the Sony Radio Awards for four years, the only woman to have done so, and the Radio Academy Festival for a decade. She lives alone, but with around two dozen radios, in Notting Hill.

David Baddiel is a comedian and writer. Known both for his solo work and for his comedic collaborations with, among others, Rob Newman and Frank Skinner, he has also written a screenplay, a musical and several books. Born in 1964 to Jewish parents, the second of three boys, he was brought up in Dollis Hill, London. His father was a scientist from Swansea and his mother was a refugee, whose family had to flee from Nazi Germany. When David was 13, his older brother Ivor played him sketches by Derek and Clive which kindled his appetite to become a comedian.

He read English at Cambridge and became vice-president of the Footlights before starting out on the London comedy circuit. Together with Steve Punt, Hugh Dennis and Rob Newman, he was part of The Mary Whitehouse Experience for Radio 1 and later BBC 2. Rob and David went on to create Newman and Baddiel in Pieces, and were the first comedians to sell out Wembley Arena with a gig in 1993, prompting newspapers to declare comedy "the new rock 'n' roll". David then formed a comedy partnership with Frank Skinner and they hosted Fantasy Football League and later Baddiel and Skinner Unplanned. They co-wrote the lyrics to one of the best-known football songs, Three Lions.

In 2005, David took a break from performance and concentrated on writing novels for adults and children's books as well as the script for a film, which became a musical, The Infidel. He returned to stand-up in 2013 with a show about fame. He recently mined his parents' idiosyncrasies and the rare form of dementia from which his father suffers for a stand-up show entitled My Family: Not the Sitcom. His partner is fellow comedian and writer Morwenna Banks. They have two teenage children.
