Graeme McCormick has pulled out of the race to become SNP leader and instead endorsed rival John Swinney as Scotland’s next first minister.
Mr McCormick’s decision not to pursue a leadership bid leaves Mr Swinney as the only official candidate after Humza Yousaf announced he is stepping down.
Mr Yousaf said he was resigning last week after he decided to end the power-sharing agreement with the Scottish Green Party.
In a statement shared with Sky News, Mr McCormick, a party activist, said he had had a “lengthy and fruitful conversation” with Mr Swinney, adding that he had “met the threshold set by the party rules”.
“John and I agreed the challenges which the SNP, our government and our people face, and explored new thinking on a range of issues which I am confident, as they are advanced, will inspire activists both within the SNP and wider independence movement in the following weeks and months,” he said.
“This is a fresh start for our members and our politicians, and I’m sure that John’s determination to deliver Independence will be rewarded at the forthcoming general election.
“I have therefore concluded that I shall not proceed with my nomination for party leader but instead support John Swinney’s nomination for party leader and first minister of Scotland.”
It means the party will avoid a three-week leadership contest, which would have been triggered had Mr McCormick not stepped aside and received. the required 100 nominations.
