Tony Blair will quit Downing St on the morning of 27 June. We all recall those stage-managed images of him entering through rapt crowds waving union jacks. Well, it is time for the reverse image as we boo the old warmonger out. I do hope you will join me there. Blair’s leaving will be covered worldwide and it is a great opportunity to get our point across. It was Blair’s support for Israel’s invasion of Lebanon, against the whole background of the war in Iraq, that led the Labour MPs to boot Blair out. We should remind the World why he has to go.

It needs enough people that the media cannot ignore it – and a determination not to be shunted somewhere invisible.

(I have, incidentally, no idea why the Stop the War Movement is dissipating energy on yet another long traipse in the rain around the deserted parts of Manchester three days previously, which will get no coverage at all.)

I have been determinedly trying to give Gordon Brown the benefit of the doubt. Sadly his strong support for anti-civil liberties legislation seems to leave little room for doubt. The need to maintain the right to demonstrate is another good reason to be there. Military Families Against the War have a permit for the demo.

We have already had a preview of the kind of hagiographic, cult-of-personality type reviews the BBC will be pumping out. When Blair announced his departure a month ago, the BBC produced a montage of his premiership that ignored the anti-war movement, cash for honours, the Mandelson/Blunkett resignations, the Lebanon, the Bernie Ecclestone scandal, David Mills or anything else that might be viewed as negative – or balanced.

Doubtless the Labour Party will have laid on some pro-Brown demonstrators. Let us make sure that those who hate what Blair has done to this country are represented in waving him off.

Be there. Downing Street. 27 June. 10am.
