Scotland's first minister Nicola Sturgeon resigns

The deputy first minister John Swinney has written on Twitter: "I am very sorry Nicola Sturgeon has decided to step down as first minister and as SNP leader.

"She has given outstanding leadership to our country, government and party."

He says she has "achieved much" particularly with her leadership during the Covid pandemic.

"She has delivered breath-taking electoral success, winning every election during her leadership, and securing two Scottish Parliament victories," he added.

"It has been my privilege to support her as deputy first minister.

"She has my warmest good wishes for the future and heartfelt thanks for all that she has done for Scotland, for the cause of Independence and the Scottish National Party."
