Alex McLeish's second spell as Scotland manager is over.
The Scottish Football Association announced McLeish would be leaving his role "with immediate effect" after board members gathered for a meeting at Hampden on Thursday morning.
SFA chief executive Ian Maxwell said in a statement: "The decision to part company was not an easy one, especially given Alex's status as a Scotland Hall of Fame member, earning 77 international caps, having played in three World Cups and taken charge of the national team for two spells.
"It was only taken after full consideration by the board and after an honest and respectful conversation between myself and Alex earlier in the week.
"Ultimately, the performances and results as a whole in the past year - and, in particular, the manner of the defeat in Kazakhstan - did not indicate the progress expected with a squad we believe to be capable of achieving more."
Alex McLeish has been confirmed as the new Scotland manager.
The 59-year-old described his return to the role he vacated in November 2007 as a "tremendous honour".
In a statement released by the Scottish Football Association, McLeish added: "I am incredibly fortunate to have had the chance to lead my country already and I am immensely proud to be in this position for a second time."
McLeish replaces his former Scotland and Aberdeen team-mate, Gordon Strachan, who lost his job after the nation's exile from a major tournament passed the 20-year mark.
He said: "There is much to be positive about in Scottish football, with players playing at the highest level and promising talent breaking through.
"With Hampden Park as one of the host venues for Euro 2020 we have an amazing opportunity to showcase our talents to the world from our own back yard. I am relishing the challenge of leading us to a major tournament and I cannot wait to get started."
