Thursday 3 May: Welcome to the BBC's election coverage, with live updates of results and commentary from the local elections in England, Wales and Scotland, and mayoral elections in London, Liverpool and Salford.

The SNP will be hoping they can maintain their momentum after last year's spectacular Scottish Parliament victory. This year will see many close battles, particularly against Labour, and much talk ahead of the polls has been about the critical battle in Glasgow. Labour require a single gain to take control whereas the SNP would need a substantial 19, but the SNP gained five Scottish Parliament constituencies from Labour in the city last year, reducing it to three - so it's not beyond the realms of possibility.
