Nick Clegg has ruled out using his wife's popularity to improve his public image during the election.
The Deputy Prime Minister revealed the secret of his marriage to Miriam Gonzalez Durantez is "laughing a lot and having big arguments".
In a joint interview with his wife, the Lib Dem leader told Red Magazine: "We're husband and wife.
"I don't think of Miriam as some sort of PR seesaw. It would literally never occur to me."
The pair have been married since 2000 and have three sons. Explaining the success of their relationship, Ms Gonzalez Durantez said: "I think the secret is laughing a lot and having big arguments. If you can get over that before you go to bed, that's fine."
They met when they were students in Bruges and, according to Mr Clegg, it was "total thunderbolt stuff" - even though they had to communicate in French as they did not speak each other's language.
Both the Deputy Prime Minister and his wife, an international lawyer, share childcare duties for their three sons Antonio, Alberto and Miguel, but Mr Clegg admitted: "I'm afraid equality does not prevail in the kitchen."
Ms Gonzalez Durantez, a partner with law firm Dechert, said: "I believe that every single woman can choose what they do with their lives - as men do - and not have to give explanations to society about what they have chosen. That's that."
