Scottish Conservative Leader Douglas Ross said:
“I wish Liz Truss and her family well.
“No matter where you stand on her decisions as Prime Minister, politics can be very tough on people personally.
“She has made a difficult choice but it is the right decision.
“There were no other options after recent events.
“We must now move forward quickly with the election of a new Leader and Prime Minister to restore stability for the good of the country.
“It is vital that the Conservative and Unionist Party unites and continues the hard work of getting the whole of the UK through the big challenges we face.”
