Part 1

Huw Edwards and Kirsty Wark are your guides as the votes are counted in this year’s bumper set of elections.

BBC correspondents will be at all the key counts to bring you the latest results from the Scottish Parliament and Welsh Senedd elections – and from all the key contests for local councils, mayors and police commissioners across England.

With Kirsty Wark in Scotland, David Wallace Lockhart will watch the story unfold on his giant virtual map of the country.

With Huw Edwards in London, Reeta Chakrabarti will analyse all the numbers at her giant touchscreen, and Professor Sir John Curtice will assess the underlying electoral trends.

The BBC’s political editor Laura Kuenssberg will be at Westminster to bring you the latest political reaction to the results.
