Cameron: Possibility of limited change in the future

The prime minister responds to the threat to the government from rebellious Tory MPs ahead of tonight's EU referendum vote:

"I think this is the right time to sort out Europe's problems, sort out the eurozone problem, defend your national interest, and look to the opportunities there may be in the future to repatriate powers back to Britain.

"Obviously the idea of some limited treaty change in the future might give us that opportunity."
