The two main parties have been punished over Brexit by voters who took to the polls for the local elections, with both Labour and the Tories suffering early losses.
The contests across England and Northern Ireland come as the Government remains engulfed in controversy following the dramatic sacking of Gavin Williamson as Defence Secretary.
Prime Minister Mrs May has also been under fire from Brexiteers for delaying the UK’s exit from the EU until the end of October.
The Tories fought the elections amid predictions the party could lose more than 800 seats. Elections took place in 248 English councils outside London, and 11 local authority areas in Northern Ireland.
There were also polls for six elected mayors in Bedford, Copeland, Leicester, Mansfield, Middlesbrough and the new North of Tyne devolved regional authority.
