So the battle has been joined and the great fight for the future of our country has begun. On June 23rd we will make the most important political decision in our lifetimes.

I am determined to do all that I can within my powers to win.

The Grassroots Out (GO) event at the QE2 centre on Friday night in Westminster was a remarkable occasion. Over 2,000 people were crammed into the venue, with 300 shut outside due to fire regulations.

I have never felt such an electric buzz at a political meeting. These people want change. They want their country back.

From the formation of GO, we have sought to be a genuine cross-party campaign and pledged to put aside all of our previous quarrels and differences. The British media too often portray the Eurosceptic camp as being purely a Tory right of centre debate.

It is no such thing. The traditional differences between left and right are irrelevant. This is about right and wrong.

For GO to win the Electoral Commission’s designation and for us to win the referendum we need millions of people on the left of politics to join our great cause. With the excellent Labour MP Kate Hoey being a founder member of GO, this strategy got off to a good start.

On Friday I surprised, perhaps even stunned, some of my long term supporters by introducing a surprise guest: George Galloway.

On a whole host of political issues George and I are diametrically opposed. We could not have a cosy chat over coffee about Israel, economic policy or a host of other issues. But sometimes in life an issue comes along that is bigger than anything else and traditional opponents become allies.

Churchill despised Uncle Joe Stalin as much if not more than he did the German corporal. But they joined together to defeat a common enemy. It is that same understanding that George and some in GO have today.

We believe in our country and that it should be run by our own people through the ballot box.

We will all fight side by side to win this referendum and then to get back to opposing each other.

It’s called democracy. It’s worth fighting for. Come and help us.
