Profile

The newly-appointed British ambassador to the United States, Sir Christian Turner, is a career diplomat whose experience spans almost three decades. He was about to take up the role of the UK's ambassador at the UN but after Lord Mandelson was abruptly pulled from his ambassadorial role in the US late last year, Sir Keir Starmer diverted Turner to replace him. Born in Crawley in 1972, Turner attended the prestigious Marlborough College, before pursuing English literature at the University of Manchester, and later a doctorate at York. After flirting with documentary-making, he pivoted to public service, entering the Cabinet Office in the late nineties. He has closely advised several prime ministers, including Theresa May with whom colleagues say he shared his love of card games.After an initial posting to Washington ended in 2006, his career has flourished at the foreign office.

The new Mayor of New York and at just 34, the youngest since 1892, is sworn in. He is the first Muslim and Indian American to lead the nation's largest city. Zohran Mamdani was born in Uganda, Africa, to parents of Indian descent and it was a childhood filled with bird song and nature. He was seven years old when his family moved to New York, to Manhattan's Upper West Side and that's where Mamdani began to make his mark. He started making music as rapper, Mr Cardamom but after releasing only a few songs, it seemed politics was a better fit. Zohran Mamdani ran an impressive campaign, recruiting an army of volunteers 100,000 strong to pound the pavements and knock on doors. His social media videos in multiple languages credited with vastly increasing voter turnout from a range of South Asian communities. A left-wing democratic socialist, his message was laser focused on affordability; he promised to freeze the rents and make buses free, all paid for by a tax on New Yorkers making over $1 million per year. But now he's won the election can he actually deliver on those promises? Mark Coles hears from Mamdani's mother the filmmaker Mira Nair, colleagues and journalists to find out what shaped the man making history.Contributors Mira Nair - film maker, mother Hari Kondabolu - standup comedian, friend Prof Brian Purnell - chair of the Africana Studies Department at Bowdoin College Cassie Wilson - volunteer for Mamdani's campaign, content creator and comedian Jagpreet Singh - political organiser for South Asian communities in New York, DRUM Beats Nada Tawfiq - BBC Correspondent in New YorkProduction Presenter: Mark Coles Producers: Phoebe Keane, Ben Crighton, Natasha Fernandes and Tom Farmer Production Coordinator: Maria Ogundele Sound: Gareth Jones Editor: Justine Lang

Karl Bushby, the British man walking around the world, is almost home. The former paratrooper set off from Chile in 1998. He walked through the Americas, crossed the frozen ocean from Alaska to Russia, and last year became the first person to swim the Caspian Sea between Kazakhstan and Azerbaijan. These are all huge achievements in their own right but for Bushby they were just sections he had to complete to finish his epic journey. Originally scheduled to finish in 2006, Bushby is now 56 and still going. Geopolitics has played its part, with Russian and Iranian visa rejections some of the main causes of delay. He arrived in Budapest last month and with the English Channel being the only obvious remaining obstacle to navigate, he should be back in Humberside by this time next year. Stephen Smith finds out who he is and what's kept him going for so long.

She struggled in school and studied Home Economics class instead of Maths.Berry left school with no qualifications but continued to pursue her love of cooking, training at the famous Le Cordon Bleu school in France. In 1971, she began her TV career with slots on shows like Collector’s World and Good Afternoon with Judith Chalmers, where she’d teach viewers how use newfangled items like freezers and tinfoil.Over the next four decades, Berry would go on to write dozens of cookbooks, feature in and present her own cooking programmes, and teach thousands to cook in her Aga lessons, which she hosted in her own home. But it was her role as a judge on Bake Off that introduced her to a new generation of viewers, and cemented her as one of the nations best-loved cooks.

David Harewood, who turned sixty this week, returns as Othello for the third time on stage. It’s a role he first took on in 1997, becoming the first black actor to play the part at London’s National Theatre. Growing up in multicultural Birmingham in the sixties and seventies, he was born to immigrants from Barbados. Described as gregarious by his teachers at school, Harewood showed an interest in entertaining from an early age and subsequently trained as an actor at the Royal Academy of the Dramatic Arts. In his early twenties, he had a psychotic breakdown, something he spoke about in a recent documentary. A string of roles in TV and film followed. And then came his breakthrough role as CIA agent David Estes in the acclaimed hit US TV show Homeland.Mark Coles looks back at his career.
