Liberal Democrat leader Sir Ed Davey is among five MPs to confirm on Tuesday they are isolating after testing positive for Covid.
He joins Labour shadow ministers Rachel Reeves, Jim McMahon and Bridget Phillipson, and Conservative MP Matt Vickers.
On Monday Labour’s Feryal Clark and Tory Darren Henry, tested positive and are self-isolating.
Some of the MPs isolating are doing so after a positive PCR test, with others isolating after a positive lateral flow test, whilst they await a PCR result.
Tory MP Dean Russell said earlier on Tuesday he was isolating after a positive lateral flow test, but later confirmed he would be returning to work in Parliament after a negative PCR test.
Confirming his result on Twitter, Sir Ed said he would be phoning voters ahead of Thursday’s North Shropshire by-election instead of campaigning in person.
