The patterns from last night seem to be a thumping victory for the SNP in Scotland, Labour heading for victory in Wales. In the English local elections the Liberal Democrats are suffering badly, facing extreme losses in Northern cities and patchier losses elsewhere. The Conservatives are experiencing modest losses to Labour, but these are being cancelled out by gains from the Lib Dems.
This afternoon we have the rest of Wales, Scotland and the locals before counting starts on the referendum at 4pm.
Finally, YouGov have released data from polling on election day (a sort of online exit-poll) here.
