Douglas Ross has been urged to attend a vote on whether an investigation should be carried out into claims that Boris Johnson misled parliament over covid lockdown breaches.
The Scottish Conservative leader is set to miss the crucial vote which would refer the Prime Minister to the Commons privileges committee.
Instead of being at Westminster Ross will be campaigning in central Scotland for the council elections on May 5 then attending First Ministers Questions at Holyrood where he will face Nicola Sturgeon in the Chamber.
