Well Mr. Cameron?

At the unveiling of the new Conservative poster/campaign for the European Elections, David Cameron said "Where you stand on the referendum says a lot about your politics."

So Mr. Cameron - where do you stand on the referendum? Is it a case that, were you to be elected to form the next government, if not ratified you will grant a referendum on the Lisbon Treaty and, if ratified you would not?

What does "We will not let matters rest there" actually mean?

At present it is obvious no-one has any idea where you stand as you are 'sitting on the European fence' and it is time to come clean methinks. As you said: "Where you stand on the referendum says a lot about your politics."
