SCOTLAND’S Minister for Social Security Ben Macpherson has ruled himself out of the SNP leadership contest amid speculation he would run. 

Writing on social media, he said he had been “uplifted” by all those who had encouraged him to run and that he had “considered seriously” whether or not to launch a bid. 

As things stand, only three candidates have declared themselves to be in the race – Humza Yousaf, Ash Regan and Kate Forbes. 

Macpherson said: “I’ve been uplifted by all the people (within & outwith @theSNP) who’ve been in touch in recent days encouraging me to stand in the leadership contest. 

“I’ve also considered seriously if the situation would benefit from the inclusion of a fourth option/another progressive choice.”

He added that he believes he has “more to contribute” having served “effectively” in various ministerial roles over the past four years. 

He continued: “For various reasons I don’t feel that now is the right time in my life & development to put myself forward for such a responsibility & challenge.

“I’ll continue to work to progress positive change for Scotland.”

Macpherson also called for a “respectful and honest debate about building on our strong record, how to realistically and effectively bring about constitutional change and bring people in Scotland together as we move forward”. 

Candidates have until Friday to receive more than the threshold of 100 nominations from at least 20 local branches. 

If more than one candidate should pass that mark then an election will be triggered, culminating on March 27.
