Diplomatic police due to embassies. The street also backs on to Kensington Palace so will part of the wider cordon for that.

Yeah I’ve just read they are Diplomatic Protection Group police, so perhaps they ignored the lads with swag bags.

I used to walk down there on my way back from the student bar at uni. Would often stop for a pee in one of the fancy front gardens. Never any hassle from the armed guards

I was broken into once. Luckily my neighbour disturbed them and they only got away with a pile of old porn mags. It doesn’t matter what the value of the stolen property is, it still hurts.
