David Cameron said: "We are married, not to each other. We are both happily married and this is a government not a relationship. It's a government about delivering for people because of the mess we were left in by the previous Government.
"And what we said to people two-and-a-half years ago is that we would come together for a five-year Parliament. We would tackle these problems. So, to me it's not a marriage it is a Ronseal deal - it does what it says on the tin.
"We said we would come together, form a government, we said we'd tackle these big problems, we said we'd get on with it in a mature and sensible way - and that is exactly what we've done."
