Special election episode with an in-depth look at the election in Wales, with contributions from Scotland and England.

It's a special election programme this week, with Professors Richard Wyn Jones and Ailsa Henderson and the BBC's Alex Forsyth dissecting the polls and ups and downs of the parties ahead of the Senedd, Holyrood and English local government elections. We'll have watchers of all colours telling us how the campaign has gone for them on the ground: Leanne Wood, Mark Williams, Sean Morgan, Wayne David, Gawain Towler and Lauren McEvatt.
