Michael Gove, now Lord Gove of Torry in the City of Aberdeen, was a cabinet minister under David Cameron, Theresa May, Boris Johnson and Rishi Sunak. He ran to be leader of the Conservatives twice, famously killed off Boris Johnson's first tilt at the top job but backed him on Brexit, spectacularly falling out with David Cameron in the process in a drama portrayed in sometimes excruciating detail in a book by his ex-wife Sarah Vine. He has now gone back to his first trade of journalism as editor of the Spectator magazine.

Jacinda Ardern is arguably the most globally famous and lauded New Zealand Prime Minister of modern times.

Her international profile began with her being the world's youngest head of government at thirty seven, who within months had a baby and took it all in her stride.

But it was her response to the horrific terrorist attack on mosques in Christchurch that gave her hero status amongst progressives around the world - embracing the muslim community in New Zealand and passing strict gun laws in response.

Her six years as prime minister also meant dealing with the covid pandemic, and the fury and conspiracy theories around lockdowns and vaccines that came with it - many of which targeted her personally. And then in January 2023 - as suddenly as she had arrived on the global stage, she stood down. Her book, A Different Kind of Power, is perhaps the most sensitive and candid account of a leader you could ask for, framed around her desire to be remembered for her kindness.

He is known for pushing boundaries with his intelligent, self-referential and often provocative style of comedy but in his new show 'Stewart Lee vs the Man Wulf' he questions his place on the comedy circuit in an era of increasing populism rhetoric and the popularity of, in his words “$60m Netflix comedians of hate.”
