Eurosceptic Conservative MP Peter Bone has told Daybreak that the party is united behind calls for a referendum on the EU.
He said: "What David Davis is saying is what many others have said. Demanding action in this parliament guaranteeing a referendum in the next parliament."
Political commentator Andrew Pierce added: "They [the Tories] do not want any more powers. They want to take powers back from Brussels. It's Labour who are divided."
