RUTH Davidson must quit the Scottish Parliament if she accepts a peerage, an SNP MSP has said.

The former Scottish Tory leader is reportedly set to be appointed to the Lords after being offered the role by Boris Johnson.

SNP MSP George Adam says Davidson must resign from Holyrood if she takes up the Westminster position.

He said: “If this speculation is accurate then Ruth Davidson needs to stand down from the Scottish Parliament and allow the people of Edinburgh Central to be represented by someone who treats it as a serious, full-time job, instead of by a part-timer who continues to pocket an MSP’s salary.

“Ruth Davidson has never shown a shred of political principle, going from the darling of the Remainers to a born-again Brexiteer without missing a beat. Her botched bid to accept money from a lobbying firm while sitting as an MSP shows that she is not remotely serious about representing her constituents.

“With this reported peerage, Ruth Davidson is now set to be rewarded for failure – being handed a fat salary and a permanent place in parliament without having to answer to constituents.”

Davidson, who quit as Scottish Tory leader in August, is due to step down as an MSP next year ahead of the Holyrood election.
