In a special hour-long programme at 10.30pm, we'll be analysing the results of the UK local, Welsh, Scottish and AV polls. Our political editor Michael Crick will bring us the latest on the AV result which is still coming in, and will be assessing where heavy losses for the Lib Dems in England, significant wins for the SNP in Scotland, and the Conservatives holding ground in England all leaves British politics.
David Grossman is in Bristol asking Lib Dem grassroots supporters how their party blew their big chance to get electoral reform, and what they should do now in coalition. Iain Watson reports from Edinburgh on the SNP's surge to Holyrood victory.
And we'll be joined by Danny Finkelstein, Olly Grender and Peter Hyman to chew over the events of the day.
