What are the most dangerous UK cities?

This is not a hard question really well i know how London is so would definitely pick London LOL Southampton is cool but it might be a bit boring too. I usually go out at night here in Southampton there is no problem at all. Town is pretty small and safe as well basically its just full of students. But some areas in Birmingham are proper ghettos, and that city is a total **** hole i will never live there to be honest even i get paid.
