A look at the life of Matt Hancock, Secretary of State for Health & Social Care for England. He has been criticised for promises he's made about testing and supply of personal protective equipment for health workers. According to newspaper reports, unnamed Downing Street sources have been suggesting the targets are "arbitrary" and "irrational". Mark Coles talks to friends, family and his mentor - the former Chancellor George Osborne - to find out more about Matt Hancock. An expedtion to the North Pole, a game of cricket on the Arctic ice, a stint as a sports broadcaster - it's not what you might expect.

Dame Vera Lynn's story is well known. She's regarded by many as one of Britain's national treasures. Dubbed 'the forces sweetheart' during the Second World War, her songs like 'We'll Meet Again' and 'There'll Always Be An England' became synonymous with hope and survival during dark times.

On Profile this week, we look at the man who has effectively become Britain’s acting Prime Minister.

The 46-year-old Foreign Secretary, Dominic Raab, asked to deputise “where necessary” for Boris Johnson while he recovers from coronavirus.

A staunch Brexiteer and a karate black belt, he’s perhaps not the best-known member of the Cabinet.

So, who is he and – more importantly - is he up to the job?

A former lawyer, Raab has experience in international justice – but his hard-line on Brexit as well as past comments about feminism, welfare and Britain’s work ethic have angered his critics.

Mark Coles hears from political colleagues, Westminster journalists – even Dominic Raab’s boxing coach.

On Profile this week - it’s a personal one.

In lockdown at home because of the coronavirus, presenter Mark Coles has turned to music to help get him through the past few days…captivated by an album he bought by chance in a London record store a couple of weeks ago.

It’s called‘Esja’- the debut album from a little-known 29 year old Polish pianist, Hania Rani.

The music is sublime and minimalist…solo acoustic piano inspired in part by the mountains and countryside of Iceland where some of it was recorded.

For Mark, it’s become his sanctuary….his headspace - a much needed nightly respite from the cacophony of coronavirus news bulletins and press conferences.

But who is the mystery woman behind the music?

The Home Secretary Priti Patel has been accused of bullying civil servants.

The Cabinet Office is investigating several allegations about Ms Patel's behaviour, all of which she denies.

Sir Philip Rutnam, the Home Office's most senior official, resigned on 29 February, alleging Ms Patel's conduct towards staff included "swearing, belittling people, making unreasonable and repeated demands". Since then, similar allegations have emerged from the Department for Work and Pensions and the Department for International Development.
