Pro-Palestinian protest draws 300,000 in London, as police make counter-protest arrests - BBC News
Huge crowds marched through central London amid a major policing operation in the capital.
It’s rare for journalists to be allowed into the Met Police’s control room - especially when there is a major operation under way.

Even when it happens there are conditions. It’s supposed to be at a secret location. I can say it’s in Lambeth - that’s about it.

And operational information displayed on screen and whiteboards in front of dozens of officers and staff is not for publication.

But a visit offers a fascinating glimpse at the surveillance possible in modern Britain.

We were shown live pictures from a police helicopter above a pub. The camera’s lens was powerful enough to show a man sitting in the window. We could see what drink he was enjoying and how much he had left in his glass.

There are thousands of cameras in London - belonging to the police, TfL, and local authorities, and the Met has access to them all.

Senior Met figures were also keen to point out the threat their officers had encountered today - noting in their briefings the knuckledusters, knives and class A drugs carried confiscated from counter protestors.

Many of the crowd had convictions for football violence, they added.

Remembrance Sunday takes place tomorrow. Police resources will again be boosted - but a testing weekend for policing appears to be over its most difficult day.
