The Conservatives would have a reduced majority at Westminster if voting patterns in the local elections were replicated nationally, Sky News analysis suggests.
Just over 2,000 council wards have been scrutinised – and more than six-and-a-half million votes.
The projection finds that Boris Johnson’s party would have a parliamentary majority of 48 seats – down from the 80 achieved in the December 2019 general election.
The Tories would be on 349 seats – down 16.

Labour and the SNP would be up slightly on 206 seats and 50, respectively – a rise of three for Sir Keir Starmer’s party, and two for Nicola Sturgeon’s.
The biggest beneficiaries would be the Liberal Democrats – doubling their representation from 11 seats to 22.
In the Sky News model, the Lib Dems are taking seats from the Tories.
Election analyst Michael Thrasher said he would be “delighted” by the figures if he was a Conservative, while for Labour, they simply add to “the doom and gloom”.
Explaining his reaction to the Tory projection, he explained that the “two main parties lose votes in local council elections, and the Liberal Democrats and other smaller parties – for example the greens – they improve”.
The projections “need to be considered in light of those conditions”, he added.

“If I was a Labour supporter, it simply adds to the doom and gloom the party is probably feeling at this point,” he said.
“The 2019 general election was Labour’s worst result since 1935, and this only gives them three extra seats, so it really is pretty dismal for (them).”
As of 4pm on Saturday, the Conservatives had increased their number of English councils by nine, while Labour was down by four.
But Labour will remain in power in Wales after winning a working majority in the Senedd.
