is duel masters popular in the UK or not especially in London

Duel Masters is popular over here in there UK. Maybe not as much as Yugioh, but it still gets a lot of play around the county. London has the biggest area of tournaments (3-4 I think) and has a lot of popularity!

i am maybe moving to london ,and i was youst wondering if it was popular over in london thanks for your reply.

In my opinion, it'll soon be popular nearly everywhere.

Yeah most times you search for uk tourneys they are London based with the odd one at plcaes like psisoft and bishop in nailsworth and coventry respectively. I shouldn't think you'd have trouble finding a competitve environment there.
Might be best to ask someone that lives there.....
