Nick Clegg's wife has insisted the couple cope with all the political barbs directed at her husband by "standing together" and by not taking them too seriously.

Miriam Gonzalez Durantez has hit the campaign trail, claiming the Liberal Democrats "deserve" to be re-elected in May after putting the country above their party for five years "at great personal cost".

In yet another soft-focus campaign interview, this time for ITV's Tonight programme, Ms Gonzalez Durantez explained how the Cleggs came under a lot of pressure to move into a grace and favour government-run house when the Coalition was formed but refused to do so.

"If you look at it with perspective it has been the best decision for all of us and, if I may(say), also for Nick as well, because you can see how politicians sometimes can get in a bubble and be completely distant from normal society and if you're in your house in your neighbourhood, it's much easier really."

Asked about how she coped with the personal abuse heaped on her husband, she replied: "Just like any other marriage; we just stand together and it's not any more of a difficulty than what many others have to go through and, you know, you should never take it too seriously."

Questioned about the negative headlines, Mr Clegg said: "I don't read all the papers."
