I was not there in London today (although I was protesting in Cambridge's market square and helping organise tomorrow's Hiroshima memorial day too) so I have absolutely no idea how many were protesting.
Indymedia tell me two people were arrested sitting down outside Downing Street (here), now it's gone upto seven (here) Reuters tells me there were mass protests all round the world - particularly the Middle East - and that in London "Police said around 15,000 people were marching but organisers put the number at more than 100,000." (here)Some people think that "100,000 is a cautious estimate by STWC" (here) because the StWC are well known for their caution when it comes to estimating numbers of protesters. Others outragiously believe that organisers of demonstrations puff the numbers attending - but of course these people are nothing but lackies of Mossad, or something, I expect.
My personal formula - which is excedingly scientific if you please, is that I take the organiser's number, average it with the police estimate, and then compare it with what I reckon. This would make about 60,000 which is very, very good.
The other little issue is around what kind of demonstration was it. I well rememeber the enormous 1.5 million demo on Feb 15th three years ago.
One of the most boring days of my life. Standing around in streets so packed you can't move for hours on end. Other (much smaller) demos have been full of fighting spirit, or hostile to the left, or like a massive stroll before a picnic. The demographics of age, ethnicity, class composition are also often very interesting.
I've heard some complain about the slogan "We are all Hezbollah" which I suppose is factually inaccurate. I'd be interested to hear of any eye witnesses to the demo - what you thought about its size, politics and how it actually felt to be there.
Demo Pics: here, here, here, here, here, here, here, and the BBC report
