The transport secretary's critics call him “failing Grayling" - an unkind nickname, perhaps, but one made more likely to stick by his infamous decision to award a valuable contract to a Brexit ferry company with no ferries. He cancelled the contract this week amid much derision in Parliament. Presenter: Mark Coles Producer; Sally Abrahams

Juan Guaidó - who recently declared himself Venezuela’s president - was elected to the National Assembly in 2011 and won the seat of his home state in 2016. But he only really came to prominence more recently when he was picked to head Venezuela's parliament, the National Assembly. US President Donald Trump has recognised Guaidó as the country’s legitimate leader - as has Canada, Brazil, Australia and the European parliament - but, for now, Nicolás Maduro is showing no signs of giving way. In this edition of Profile Edward Stourton traces Guaidó’s life and hears from his family, friends and those who have followed his career. Guaidó grew up in the beachside state of Vargas where his family survived the horrendous 1999 mudslide tragedy. Juan’s mother, Norka Marquez, tells Edward how her family lost everything in that disaster.Producer: Darin Graham

There’s only one story this week. People up and down the country are bitterly divided. Yes, it’s the vegan sausage roll. The latest PR-friendly innovation from bakery-turned-fast food chain Greggs. But the success of this faux meat pastry product is just the latest chapter in what is one of the retail turnaround stories of the past decade. Down in the doldrums five years ago these days Greggs is on a – ahem – roll. And it’s largely down to one man, apparently: Roger Whiteside, our subject this week.Presenter: Mark Coles Producer: Smita Patel

On Profile this week, Mark Coles looks at the most powerful woman in American politics – the veteran Democratic congresswoman and new Speaker of the United States House of Representatives, Nancy Pelosi.It’s a remarkable comeback for her…it puts her third in line to the Presidency itself. Having first done the job back in 2007 when George W Bush was Commander in Chief – now 78, many thought Pelosi was too old this time round. But only a week into the role, she’s already engaged in a bitter war of words with President Trump over his demand for Congress to fund his Mexico border wall. For many, with the Democrats now controlling Congress, Nancy Pelosi is set to become the face of opposition to the President for the next two years. We hear from childhood friends, former colleagues and those who’ve followed her career down the decades.From campaigning for her dad when he was Mayor of Baltimore back in the 1940s to helping President Obama reform American health care, we examine Nancy Pelosi’s life and career and – in these turbulent times – look at the challenges that lie ahead for her.

Melania Trump is the second foreign-born First Lady and Donald Trump’s third wife; an ex-model, 24 years his junior, who once posed pregnant in a gold bikini on the steps of her husband’s jet. It was modelling that took Melania from small-town Slovenia to New York and her fateful encounter with the future President. But despite being one of the most recognisable woman in the world she remains something an enigma. So who is Melania Trump? What does she believe? And what might she do on the global stage which – however improbably, given her origins in far away Slovenia – she now shares with the President of the United States?
