Britain's main opposition leader, David Cameron with his spouse, Samantha Cameron. LONDON (AP) — The wife of Britain's main opposition leader David Cameron disclosed Saturday her husband unwinds with "The Godfather" movies, and pledged to help the aspiring leader make U.K. voters an offer they can't refuse.

In a first major interview, the 38-year-old Samantha Cameron said her husband — head of the opposition Conservative Party — was messy, often irritating, obsessed by his BlackBerry, but ready to oust Prime Minister Gordon Brown and lead Britain.

The rare public appearance of Mrs. Cameron, a distant descendant of King Charles II, comes ahead of an election in which leaders' spouses will play a greater role than ever before in attempting to rally support for their partner.

Brown's wife Sarah has used public speeches, and frequent postings to her Twitter account, to corral support for leader. Cameron said his wife — creative director for stationery brand Smythson — will make a number of appearances on the campaign trial once Britain's election race formally begins.

Britain must hold an election by June 3, and Brown — who decides when it will take place — is expected to pick May 6 as polling day.

In an interview being broadcast Sunday, Cameron's wife told ITV television that her husband relaxed by cooking, tending to their two children, and watching his favorite movies: Westerns or "The Godfather" series.

"He's definitely not perfect and like any husband he has lots of very irritating habits," she told ITV, which released excerpts of the interview in advance.

"He is not very good at picking up his clothes. He's a terrible channel flicker. I have to be quite firm about him not fiddling with his phone and his BlackBerry too much because it can be quite annoying," she said.

In the same interview, Cameron spoke about the death last year of the couple's 6-year-old son Ivan, who suffered from cerebral palsy and a rare and severe epilepsy condition.

"After Ivan died, I did stop and think, 'You know is this what I want to do, is this life?' And I took some time off, maybe I probably should have taken a bit more off. It's an enormous shock, I came through clearer, thinking, 'This is what I want to do, this is what I am about, these are the things I care about'," Cameron said.

He also rejected claims that a recent poster campaign featured an airbrushed image of his face. "The picture was not actually airbrushed, I am afraid I have a baby face, I can admit here. I am afraid that is what I look like," he said.

The interview with the Camerons follows an emotional prime-time TV interview Brown gave last month, in which he discussed the trauma of his newborn daughter's death in 2002.

Cameron's Conservatives have led Brown's governing Labour Party in opinion polls for more than two years, but the gap between the parties has recently narrowed — raising the prospect that neither will win an outright majority at the election.
