He's going to renegotiate with Brussels and " when the renegotiation is complete, probably around 2018, he’ll put the results to the British people "
As anyone with a passing knowledge of the EU knows there's no room for renegotiations with Brussels unless you use Article 50 and declare that you're leaving. The Lisbon Treaty is watertight on that score.
But the EU will be on life support by 2018 anyway and I doubt if we'll need a referendum to leave.

Hang on. I remember now. Cast iron it was as well....
" Today, I will give this cast-iron guarantee: If I become PM a Conservative government will hold a referendum on any EU treaty that emerges from these negotiations. No treaty should be ratified without consulting the British people in a referendum"
Yes it's all coming back to me now...
