Opinion polls suggest that Britain could be heading towards its first hung Parliament since the fall of James Callaghan's Labour government in March 1979.

But for the Scottish Parliament, such dramas are only a vote away. Last year, Alex Salmond's Scottish Nationalist Party government came within an ace of falling, when Labour and the Lib Dems joined forces to vote down the Budget.
