Scottish Rugby have announced that Scotland head coach Frank Hadden has stepped down from the position with immediate effect.
The decision was taken after a meeting of the Scottish Rugby Board.
Scottish Rugby chief executive, Gordon McKie, said: "Following a presentation at today's Scottish Rugby Board, covering a review of the Scotland performance in the RBS 6 Nations Championship, it was agreed with Frank Hadden that a change in head coach is required to allow us to plan fully for the 2011 Rugby World Cup in New Zealand.
"On behalf of the board, I have thanked Frank for his hard work and commitment during his term as national coach."
Scottish Rugby will begin the recruitment process for a new head coach with immediate effect.
The demise of Hadden will come as no surprise to followers of Scottish rugby.
His position was under threat after another disappointing Six Nations tournament. Scotland failed for a third straight season to achieve their own stipulated minimum requirement of two championship victories.
Scotland have finished in the bottom two of the Six Nations five times in the last six years, which is the same record as Italy.
Their 26-12 Calcutta Cup defeat by England in the final game of this season's competition was Scotland's 12th in their last 16 matches.
Andy Farrell admits the process of selecting England's 50-man training squad ahead of the World Cup was rigorous - but the backs and defence coach also revealed how tough it was to leave some stars out.
