On the eve of polling, Labour retreated from comments the leader made in the final days of the campaign that the party was on course for gains in the local authority elections.

Mr Corbyn changed tack, saying "predictions are not that important" as the party feared losses after Labour made nearly 800 gains under Ed Miliband when the seats were last contested in 2012.

David and Samantha Cameron voted at Central Hall Westminster and Mr Corbyn voted in Islington, but polling chaos in north London meant many were unable to have their say.

Barnet Council apologised after names were missing from polling lists across the area and residents attempting to cast their vote were stopped.

The council said all the updated electoral registers are now in place and people can vote as normal.
