Commenting on Nicol Stephen's resignation as leader of the Scottish Liberal Democrats, Liberal Democrat Leader Nick Clegg said:

"Nicol Stephen has been an outstanding politician and force for change in Scotland.

"As a Minister and Deputy First Minister, he played a pivotal role in showing what Liberal Democrats can deliver in Government. As a campaigner, he led the party to a stunning win in the Dumfermline and West Fife by-election, overturning a huge Labour majority.

"He is without doubt the most effective opposition to Alex Salmond in the Scottish Parliament, and his performances at First Minister’s Questions have been incisive and forceful.

"Liberal Democrats owe him a huge debt of gratitude, and I personally want to thank him for his friendship and dedication to the party. His integrity shines through in taking what must be a very difficult step, but everyone will understand and respect his decision in view of the enormous strains and pressures of combining family life with a hugely demanding role.

"He will remain an important figure in the Liberal Democrats and I look forward to working with him as a valued friend and colleague."
