How many people demonstrated on Saturday in the March for the Alternative anti-cuts march?
Estimates range from 250,000 to 400,000 - and these figures are always controversial. But in the pantheon of major demonstrations going through London, the march is near the top.
Counting march numbers is a difficult business. Official efforts go from taking an area of the march, counting the numbers in it and then extrapolating that to the whole length of the march. Other times - see the Countryside Alliance march of 2002 - protesters are counted as they pass a specific point. Either way, teh size of a demonstration can mark its success or not. But the reality is, no-one really knows. The 2003 Stop the War march brought any nubmer from 750,000 to 2m to the streets of London - the latter figure calculated by extrapolating an ICM poll of the number of people who said they had attended.
We've worked out some of the data for the major marches in the UK, going back to Aldermaston in the 1950s. It's not a complete list - let us know what you would add to it.
