169 | Who is Boris Johnson?

We try to work out what the current favourite to be next Tory  leader actually stands for.  Can his time as Mayor of London tell us what kind of PM he might be?  Will his journalistic past come back to haunt him?  Does he have a political philosophy beyond 'doing Brexit'?  Plus we discuss whether the Johnson-Trump comparisons really stand up. With Helen Thompson and Chris Brooke.

167 | Jared Diamond

We talk to the author of Guns, Germs and Steel about his new book on nations in crisis.  Jared Diamond argues that personal crises are a good way of thinking about national ones.  He tells us about one of his own personal crises and we see whether the lessons really apply to politics.  Plus we discuss what's gone wrong with political leadership in the US and we explore what it would take to tackle the global environmental crisis.

165 | The Next PM

As Theresa May's premiership gets very close to the end, we talk about who and what might be coming next.  Can her successor re-establish the authority she has lost?  Can anyone govern in this parliament or do we need a general election?  Is the age of long-serving prime ministers also coming to an end?  Plus we discuss what lessons can be drawn from the recent election in Australia: what does it tell us about the politics of climate change?  With Helen Thompson and Chris Brooke.

121 | Gandhi's Politics

David talks about the enduring influence of Gandhi with Ramachandra Guha, author of an epic new biography Gandhi 1914-194: The Years That Changed the World.  A conversation about the politics of protest, the legacy of empire and the possibility of moral leadership. Plus, what was it like having Gandhi as your father?

114 | Labour's Fault Lines

Summer's over: politics is back!  This week we return to the mystery inside the enigma that is Brexit to ask where Labour now stands.  What is the big divide in the Labour movement: Is it MPs vs leader? Members vs voters?  Young vs old?  And what could a second referendum achieve anyway?  Plus we try to make sense of the fraught fight over the definition of anti-Semitism.  With Helen Thompson, Chris Bickerton and Waseem Yaqoob.

89 | The End of the Party?

The Conservative Party now has barely 70,000 members, most of them aged over 60. Meanwhile Labour has over half a million, many of them young.  What does this mean for the future of British politics?  Can a party survive without members?  Can Labour negotiate the divisions within its ranks?  And what room is there for a new party of the centre?  With Helen Thompson and Chris Bickerton.
