Kirsty Young's castaway is the former Chief Inspector of Prisons, Dame Anne Owers.

A long-time human rights campaigner, she's spent years immersing herself in the problems of people on the margins of society. During the time she was Chief Inspector, the prison population expanded hugely. "The thing that saddened me greatly is that our prisons became better places but they also became places that soaked up a lot of money and into which we put a lot of people. My view is a lot of that money could have been better spent doing things that stopped people getting there in the first place and therefore prevented there being victims of crime."

Kirsty Young's castaway is the former England rugby captain Lawrence Dallaglio.

He was capped 85 times for England, played in three Lions tours and led his club side, Wasps, to the top of the premiership five times.

Yet, he says, he only started playing rugby seriously after the death of his sister, Francesca. She died in the Marchioness disaster on the Thames when he was 16 and her death, he says, blew his world apart.

"Losing my sister was devastating. It made me more determined to do something to bring my parents together. When I first took up rugby, I took it up not for sporting reasons, I needed something to grab onto, I needed an olive branch."

Immediately recognisable as one of Britain's most versatile actresses she's worked in television, theatre and films over the past four decades. While she's taken roles at the Royal Shakespeare Company and in big budget films, it's her instinct for TV comedy - working alongside Victoria Wood and Julie Walters - that has made her a household name.

Audiences loved the spoof soap opera Acorn Antiques and she won an Olivier Award for her role in the stage production. In the early days, though, she remembers the camera crews were unsure what was going on. "I do remember the cameramen watching what had been a very slick show up until Acorn Antiques and then just thinking, 'Why is this bit so bad? Why is the scenery swaying in the background?'"

Kirsty Young's castaway is the writer Howard Jacobson.

After many years of swiping at literary prizes, last October he walked off with the biggest one going, the Man Booker. His book, The Finkler Question, was a study of what it meant to be Jewish in England. It's a subject that has been very near to Howard Jacobson's heart. He says: "My sense of myself has always meant being on the outside. On the outside as a Jew, looking into gentile England, but also on the outside of Jewishness too. I have always felt myself to be on the outside of everything."

Kirsty Young's castaway is the journalist Jon Snow.

For the past 21 years he's been the face of Channel Four's nightly bulletins where, along with his patent enthusiasm and vigour for dissecting the day's stories, he's noted for his natty line in neckties and socks.

He's a highly experienced foreign correspondent too - he's reported from Haiti, New Orleans, Washington and East Africa among many locations. However it was in El Salvador that he found his name on the list of people who might be targeted by death squads. It was, he says, something of a 'badge of honour'. "I cry on location", he says, "and it's a good thing, because otherwise you bottle it up and come home bonkers."

Kirsty Young's castaway is the veteran Coronation Street actress Betty Driver.

For more than forty years she's been pulling pints and dishing up her hot-pot in the Rovers Return. But her career in showbusiness started decades before she took up residence on Britain's most famous street.

She was a child when her mother put her on the stage and she toured the country with an act that showcased her stunning singing voice - it brought success but not happiness. "I did it for over twenty years," she says, "and hated every day of it." Although she has been working now for an incredible 80 years, she says: "I just love work and I will never retire. They'll have to shoot me to get rid of me!"

Kirsty Young's castaway is the First Minister of Scotland, Alex Salmond.

He has spent his political life campaigning for Scottish independence. As a schoolboy he stood in classroom elections - back then, he won on the canny ticket of half-days for all and replacing the school milk with ice-cream.

He was a child when he realised he had a knack for public performance - he was a boy soprano who seemed to have a promising career ahead of him. He says: "If you can sing in front of thousands of people when you're ten or eleven then being Scottish First Minister is nothing in comparison."

Kirsty Young's castaway is Gyles Brandreth.

A former Conservative MP, he is also a some-time actor, broadcaster and prolific writer who has authored biographies, diaries, stage plays and mysteries.

Pursuing a political career has been, he says, the over-riding ambition of his life. However the happiest moment came not from politics, but when he was performing in a West End show that he had written himself. These days, his ambitions are to return to the stage and the role he wants to take on is Chekhov's Uncle Vanya.

"I have no complaints" he says; "my life has been one long series of tomato and marmite sandwiches. I've always had what I wanted."

Kirsty Young's castaway is the veteran RAF pilot Tony Iveson.

Aged 21, he survived being shot down in his Spitfire over the North Sea during his first taste of combat in the Battle of Britain. Unusually for a fighter pilot, he then went on to join Bomber Command and the famous Dambusters squadron, sinking the German battleship The Tirpitz and winning a Distinguished Flying Cross.

Aged 89 he returned to the skies, becoming the oldest man to fly a Lancaster bomber: "Well, I got out of that aeroplane and looked at it and it and thought how did we do it?" he says. "I know it was a long time ago and I was young and fit and a professional flier. But I thought about some of my friends who had been lost and it was an emotional experience."
