Election night timingspublished at 18:21 British Summer Time 2 May 2019
Polls close at 10pm, so there could be a long wait for some results.
If you're planning to stay up all night and follow the television coverage, we expect the first full councils to be declared at about midnight. (One of either Swindon Council, or Halton in Cheshire, is expected to be first to declare its results).
The most active period is between 2-3am, when more than 40 councils are expected to declare their results. This includes the big metropolitan councils of Liverpool and Leeds
About 108 English councils are expected to report by 6am on Friday. The other 140 should come in throughout Friday, until about 6pm.
Results from Northern Ireland's 11 councils are expected to take longer, because of the different voting system there.
