Mr Cameron has said his wife gives him valuable advice
David Cameron has said his wife wants to "get out there" on the campaign trail when the election is called.
The Conservative leader said Samantha Cameron had told him she was ready to help him in whatever way she could.
"You are going to see a lot more of her on the campaign trail," Mr Cameron told the Alan Titchmarsh Show on ITV1.
Gordon Brown's wife, Sarah, has adopted a higher profile in recent years, introducing her husband before each of his past two party conference speeches.
'Right behind you'
Mr Cameron has said his wife intends to continue working full-time - she is creative director of stationers Smythson - should the Tories win power.
Asked about the role she would play in the campaign itself, Mr Cameron said she would be involved.
"She said to me the other day when we were having breakfast: 'I know I work hard and I have my own business but I want you to do this, I want you to win. I'm right behind you. Tell me what I can do to help. I want to get out there.'
"You are going to see a lot more of her on the campaign trail, so Britain get ready."
In the past, Mr Cameron has praised his wife for giving him valuable advice and telling him when he was using language the public would not relate to.
Although the general election must be held by June, it is widely expected to take place on 6 May.
Sarah Brown was present in the audience when her husband gave an emotional television interview to Piers Morgan last month.
