Voting is under way in local elections across England, as well as in the Runcorn and Helsby by-election.

Due to Ofcom rules, Sky News is limited on what it can report until polls close at 10pm.

The votes mark the first electoral test for the party leaders since last year’s general election.

In total, 23 of England’s 317 local authorities are holding elections, alongside the Isles of Scilly.

The make up of around 1,270 parish councils are also due to be decided.

And six metro mayors are up for election.

The West of England, Cambridgeshire and Peterborough, Doncaster, and North Tyneside mayoralties already have a mayor in place – while Greater Lincolnshire and Hull and East Yorkshire are choosing a mayor for the first time.

Meanwhile, a by-election is being held in Runcorn and Helsby after previous Labour MP Mike Amesbury agreed to stand down following his conviction for punching a man in the street.

While this result is likely to come in overnight, most local election results won’t be known until Friday.

All voters in these elections must be over 18, and be registered.

Join Sky News presenter Jonathan Samuels and deputy political editor Sam Coates from midnight as the results start coming in. Lead politics presenter Sophy Ridge, political editor Beth Rigby, and data and economics editor Ed Conway will be taking over on Friday to report and explain what has happened.
