Charles Kennedy is divorcing his wife Sarah Gurling on Thursday, following eight years of marriage.
The former Liberal Democrat leader, who has a five-year-old son with Sarah, announced over the summer that they were separating "with great sadness".
According to sources, the divorce comes as no surprise and is due to Charles' ongoing battle with alcoholism, which also caused him to step down from the leadership of his party.
Fifty-one-year-old Charles was the youngest MP of the 20th century when he was elected at the age of 23. He became Liberal Democrat leader in 1999 before giving up the post in 2006.
