On the night the UK parliament voted for a general election, David and Helen talk to former Conservative leadership candidate Rory Stewart about the state of our democracy. Is the constitution broken? Can the Union survive? Has the Tory party changed for good? And why does he want to be Mayor of London anyway? Recorded in front of a live audience at Church House in Westminster, near enough to parliament for Rory to run out halfway through our conversation to vote, and then run back in again to carry on talking. It's all here.
