The former Liberal Democrat leader Charles Kennedy and his wife, Sarah, are to separate.
A statement issued by the couple's respective lawyers said it was "with great sadness" that they had decided to split. "In doing so amicably, our ongoing and overriding priority will obviously remain our son," it explained. "We wish this to remain an entirely private family matter."
Mr Kennedy married Sarah Gurling in 2002 and their son, Donald, was born during the 2005 general election campaign while Mr Kennedy was still party leader.
