EDIT: Changed the article from Guardian to Independent as it was a more complete, less odd article without a cookiewall.

The numbers are still unconfirmed, but having been there I can tell you it was massive and fantastic.

The police estimates of 50 000 are comically false. The truth is likely somewhere in the middle. Most likely in the multiple hundreds of thousands.

Either way, it dwarfs any of the half a dozen protests I've seen in London over the last year, and some of those were really big.
