She tweeted: "Today is a stark reminder that the UK is facing chaos and crisis entirely because of a vicious civil war within the Tory party. What a self-centred bunch they are. They all need to go, not just the PM." 

The First Minister added: "While Westminster crumbles further into chaos, with a UK government that has ceased to function, The Scottish Government will set out our budget for the year ahead - protecting public services, supporting the economy, and building a fairer country."

The Prime Minister is facing a vote of no confidence after enough letters were submitted to hold a vote of no confidence in her leadership.
