In a signed letter to The Sun, David made the following commitment:
"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."
This is a short extract of the letter:
On Monday The Sun’s image of Gordon Brown sticking two fingers up to the British public was provocative. But it was right. What a difference to Churchill. When he made that salute, it inspired this country to wipe the scourge of fascism from Europe. But for Gordon Brown, it’s a gesture to the British people saying: “I know best. Your views are irrelevant. Get used to it.”
