THE leader of the Scottish Tories may soon be facing a challenge from one of the biggest names in the SNP.

It has been reported that Angus Robertson, the former Wesminster SNP leader, may run against Ruth Davidson in her Edinburgh Central constituency seat for the Holyrood parliament.

Robertson lost his Westminster constituency to Tory MP Douglas Ross in 2017, and since then has set up the Progress Scotland research group, which works to promote the case for Scottish independence.

He told the Sunday Times, which reported the claims: “While it is an honour to be linked by others to the constituency, the nomination process has not even started.

“I am totally focused on my work with my new venture Progress Scotland, and to the challenges of impending parenthood.”

Davidson has held the seat since 2016, though the return of political heavyweight Robertson could turn Edinburgh Central into one of the key battlegrounds of the 2021 Scottish Parliament elections.

It is rumoured that former Scottish Labour leader Kezia Dugdale is also considering running in the constituency.

A Scottish Tory source said: “Earlier this year the MEP Alyn Smith was being lined up to take on Ruth. Now apparently it’s Angus Robertson.

“Who next? On behalf of the great city of Edinburgh, the Scottish Conservatives welcome them all.”
