British TV presenter Ant McPartlin has confirmed that he and his wife Lisa are to divorce after 11 years of marriage.

The 42-year-old, who is one half of TV duo Ant and Dec, announced the news on Saturday night after months of rumours regarding the couple's relationship.

A statement issued by McPartlin's representative said: "In response to the recent speculation in the media, Ant is very sad to announce that, after eleven years, he is ending his marriage to Lisa McPartlin.

"Ant asks for privacy at this difficult time, for both himself, Lisa and their immediate families.

"No further statement will be made."

McPartlin tied the knot with make-up artist Lisa Armstrong in 2006 at a star-studded ceremony at St Nicholas' Church in Taplow, Buckinghamshire.

The couple met at a roadshow in Newcastle in the mid-1990s while Lisa was an aspiring pop star in a group called Deuce, who enjoyed a couple of chat hits before breaking up.

McPartlin has often spoken of the couple’s struggle to have children.

Last year he entered rehab after struggling with a two-year addiction to super-strength painkillers following a knee operation in 2015.

"I've put Lisa through hell with mood swings and depression and how it affects you," he said at the time.

"I'm very sorry about the effect it has on partners," he added. "This kind of stuff puts strains on any marriage. In hindsight, I should have mentioned it earlier but you’re embarrassed about it."
