The BBC, like other broadcasters, isn't allowed to report details of campaigning or election issues while the polls are open.

The BBC is required by electoral law to adopt a code of practice, ensuring fairness between candidates and that is particularly important on polling day.

The code of practice is contained in more detailed election guidelines which are written and published for each election - and they include guidance about polling day, here.

On polling day specifically, the BBC doesn't report on any of the election campaigns from 00:30 GMT until polls close at 22:00 GMT on TV, radio or bbc.co.uk or on social media and other channels.

However, online sites do not have to remove archived reports, including, for instance, programmes on iPlayer. The lists of candidates in each constituency and the guide to parties' policies remain available online during polling day.

Coverage of what is happening on the day is usually restricted to uncontroversial factual accounts, such as the appearance of politicians at polling stations, or the weather.

It tends to focus on giving information which will help voters with the process of going to polling stations.

Subjects which have been at issue or part of the campaign - or other controversial matters relating to the election - must not be covered on polling day itself; it's important that the BBC's output cannot be seen to be directly influencing the ballot while the polls are open.

However, that does not mean that other politics, for instance, what happens in Parliament or political events and stories not directly connected to the elections, cannot be covered.

No opinion poll on any issue relating to politics or the election can be published until after the polls have closed.

Whilst the polls are open, it is a criminal offence to publish anything about the way in which people have voted in that election.

From 22:00 GMT normal reporting of the election resumes, with rolling coverage online and across BBC TV and radio.
