How does the BBC report polling day?published at 11:44 British Summer Time
Detailed BBC election guidelines are written and published for each election, setting out the approach it has to take on polling day.
The BBC, like other broadcasters, is not allowed to report details of campaigning or local election issues on TV, radio or online on polling day until 22:00 BST, when voting closes.
While polls are open, it is a criminal offence to report any exit polls, which aim to predict election results on the basis of surveys of how people say they have voted.
References to the local elections on the day are normally restricted to uncontroversial factual accounts, such as the appearance of politicians at polling stations, the weather, or practical information about how to vote.
Once the polls have closed at 22:00, the election guidelines no longer apply.
However, the BBC must still report the results with the impartiality required both by Ofcom and the BBC's own Editorial Guidelines.
