Our guest today is the comedian, author, actor and presenter Tom Allen. And this is a truly charming edition of Rosebud.

In this episode, Gyles meets the Secretary of State for Health and Social Care, Wes Streeting MP. Gyles hears about Wes's remarkable life story so far, which begins in a council flat in East London and ends at the highest level of government.

We've got two political interviews for you on Rosebud this week, and this is the first. In the week of his 93rd birthday, Gyles is talking to Lord Heseltine - one of the so-called "big Beasts" of the British political scene at the end of the twentieth century.

We at Rosebud are thrilled about today's guest, and we know you will be too: it's Richard E Grant. Actor, writer, influencer and star of one of the most loved British films of all time, Withnail and I, Richard talks to Gyles about his extraordinary childhood.

It's International Women's Day on Sunday 8 March, and our guest is the Labour Member of Parliament for Bradford West, Naz Shah. Naz tells Gyles her extraordinary story; about her father, who left the family when she was only six years old, leaving the children and their mother in poverty, insecurity and sometimes squalor.

In the first of our Rosebuds in the week of International Women's Day, Gyles meets Dame Mary Archer, the scientist and former Chairs of Addenbrooke's Hospitals Trust and the Science Museum Group, made a Dame for her service to the NHS.

Gyles talks the former Archbishop of Canterbury, Justin Welby, and as this is a Rosebud conversation, we begin by hearing about Justin's fascinating family story. We hear about Justin's father - the charming, but alcoholic, Gavin Welby. About his mother, Jane Portal, who had worked as Winston Churchill's secretary and also struggled with alcohol addiction.

This is a one-off episode, in which Gyles and Harriet discuss the British royal family and their future, in light of the recent scandal surrounding Andrew Mountbatten-Windsor and his arrest last week.

In this special edition of Rosebud, we celebrate the late, great, self-proclaimed cult that is Kenneth Williams - on what would have been his 100th birthday.

Julian Fellowes, the creator and writer of Downton Abbey, Gosford Park, The Gilded Age - among other brilliant television series and movies - is our guest today.

Gyles meets one of his teenage idols: the French-born ballet dancer and film star Leslie Caron.

It's almost Valentine's Day - Gyles's favourite day of the year (the old romantic...) - and we've got a special episode for you: all about love letters. We start off with some romantic Gyles and Harriet chat, featuring bunk beds, stolen glances from train carriages, and a case of mistaken identity.

Gyles has been an admirer of this guest since the 1960s: it's the great actor, Sir Derek Jacobi. Ever since he was recruited into Sir Laurence Olivier's bold new National Theatre at the Old Vic, Jacobi has been at the forefront of British acting talent.

This is an extraordinary edition of Rosebud - from the first memory to the last, it is peppered with legendary names, great artists and wild stories. Which isn't surprising, as our guest is Antony Penrose, the son of the celebrated photographer and model Lee Miller and the Surrealist artist, writer and historian Sir Roland Penrose.

Joining Gyles on this episode of Rosebud is the Leader of the Liberal Democrats, Sir Ed Davey. But this isn't a conversation about politics, it's about Ed's life, his family, his experience of profound loss, and his involvement with caring for his closest relatives.

Dame Siân Phillips transports Gyles back to her childhood in Wales in the 1930s and 40s, where she grew up in a Welsh-speaking mining village, of which she paints a vivid picture.
