I read an article about how most British police units do no carry guns so a special unit which did had to be called in. One day they will learn. Maybe.
A fair number of British police do carry guns, but it is a small percentage.
When I was a dealer, I got a sweet deal from an importer who had managed to snag Smith & Wesson model 10 London police pistols when they upgraded to the Glock 17. This was about 10-12 years ago.
Those model 10’s had British proof marks, and had lots of carry wear, but appeared to have been shot little. They were and are a wonderful revolver. I may have one or two hanging around somewhere, but I sold most of them. I think I eventually went through about two dozen of them.
