John Swinney is expected to declare his bid to become the new leader of the SNP later today, Sky News understands.
It comes after Humza Yousaf announced he was standing down as SNP leader and Scotland’s first minister following his decision last week to cut power-sharing ties with the Scottish Greens – a move which saw his leadership collapse.
Mr Swinney previously served as SNP leader between 2000 and 2004; later becoming Nicola Sturgeon’s number two from 2014 to 2023.
He is considered a front-runner for the top job once again, having garnered support from senior figures within his party, including from the SNP’s Westminster leader, Stephen Flynn.
The Perthshire North MSP is expected to make a statement in Edinburgh on Thursday morning.
However, he could face competition from the party’s former finance minister Kate Forbes, who narrowly lost out to Mr Yousaf in last year’s leadership election.
Though the Skye, Lochaber, and Badenoch MSP has not confirmed her intention to enter the leadership contest, she has so far refused to rule herself out of the race.
