Who is Douglas Ross, the resigning Scottish Conservative leader?

Away from politics, Ross is also a qualified top-level assistant football referee.

He was one of the officials for the 2015 Scottish Cup Final, assisting Willie Collum, and the 2018 Scottish Cup Final, assisting Kevin Clancy.

He has also been involved in European and International fixtures.

His sideline as a football official has caused some controversy.

He was criticised by both the SNP and Labour for missing a parliamentary debate on Universal Credit in 2017 due to his refereeing commitments.

In August 2020, he apologised for missing a VJ Day event because he had already agreed to officiate at a Scottish Premiership fixture between Kilmarnock and St Johnstone.

Mr Ross referred himself to the Westminster parliamentary watchdog in November 2021 after it emerged he had failed to record his earnings – some £28,000 – as an assistant referee in his registers of interest. He subsequently apologised.

And just this weekend he faced allegations that he used Westminster expenses to travel in his role as a football linesman.

Mr Ross said the expenses were approved by independent parliamentary body IPSA and he would have “no issue” with the expenses being examined for a second time.

In 2015 he married police sergeant Krystle Ross. The couple have two young sons, one born in 2019 and the other in 2021.
