Making Britain better

He told ITV News' Live with Alastair Stewart programme: "There's still weeks and months to go yet, but my position remains that if the ideas I'm putting forward do get widespread support, I will run as a candidate.

"But if they don't, or there's someone else who endorses them, I won't."

You can do a deal with Mother Theresa, but if you haven't got the right ideas, you are not going to contribute to the future of the Conservative party David Cameron Cameron says 'no to deals'

He said the Conservatives should "combine a commitment to personal freedom and free markets with a commitment to make Britain a better society".

"What I have been trying to do is show how a flexible modern economy and a strong society can go together as the heart of Conservatism," he added.

'No deals'
