Elections!

Here we go again! The day after Mrs May makes her announcement, we talk about what a UK election means, whatever happened to the fixed-term parliament act and what the real choices will be on June 8. Plus we're joined by historian Robert Tombs to discuss the upcoming French presidential election, and Ayse Zarakol shares her thoughts on this weekend's referendum in Turkey. Is Erdogan the winner or the loser? Elections everywhere - so much to talk about! With Helen Thompson and Chris Bickerton.
