When can we expect the first results?
With polls closing at 10pm, you might be forgiven for thinking it could take a while for the results to come through.
And while it may take some time for the larger votes to be confirmed, the first council results could come just after midnight.
There will be a steady trickle of results through the night, with councils in Hartlepool, Sunderland, Bolton, Newcastle-upon-Tyne, Portsmouith, Southen-on-Sea and Exeter all expected to delcare before 3am.
The result in the Blackpool South by-election should be announced by 4.30am.
However, larger votes such as mayoral and PCC elections will take longer than this, with Londoners having to wait until Saturday for their mayoral election result to be confirmed.
