clearly neither, because Manchester is quite obviously the best city ever.
they are most definately not the most powerful! International capital has much more power! However the british government does have alot of power for many reasons i can agree on that much but not that they are "the most powerfull people on earth"
in answer to your first question i might have to say NY due to the fact i have never been there and they have no smoking in public places
Montreal. It's the true sin city of North America. You've got great nightlife, fantastic culture, it's the former Canadian capital so it's full of history, it's culturaly diverse: mix of English-speaking and French-speaking communities, some of the best stripclubs in the world, some of the best clubs in the world (Aria, Club Stereo often listed in every single top 10, no matter what the country), some of the most beautiful girls you'll ever see. What more can you ask for?
The Americans love it because they only have to be 18 to drink...
Edinburgh is the greatest city in the world but I don't think the OP is asking for which city is nicest, he is all about power. I think Tokyo is pretty great since they have all the crazy technology.
London is a dump and the curries are awful down there. In New York, you get shot, so thats a bit of a downside. It'd probably be up North somewhere, say Chester. Either that or Monaco.
London is far superior to New York.
London is a dump compared to many places, haven't been to New York though so I cant pass comment.
I'd say either Tokyo or Hong Kong.
I prefer a lot of the Asian cities, me.
I don't think the hull people understood my joke.
