"There's no doubt the last few weeks and the events of yesterday have been difficult and bruising for the party," he said.

"But there's also an opportunity - with a new leader in place and a new chief executive in place, generally a next generation coming through.

"You've seen that with my cabinet, you've seen, of course, the Westminster leadership in terms of Stephen Flynn and Mhairi Black.

"There's a huge opportunity for us to re-energise, to refresh, and to make sure we are being as bold and as ambitious as we possibly can be for the people of Scotland.

"There are challenges, there is no doubt about that, but I am really relishing getting out in front of the people of Scotland and hopefully articulating for them what I can deliver as First Minister as well as delivering as a party and a government."

While the polling appears to suggest support for independence is stable, it has also found a fall in backing for the SNP.
