How many Nationalities?

London has always been a city of incomers, whether from nearby or further away. Its strength is its diversity.

England is really rather ghastly (outside London, that is).

I hope you are joking. England is like anywhere ... there are horrible places and nice places ... luckily I live in Dorset which is beautiful once you are out of Bournemouth (which is horrid) and is full of mostly nice people ... but I will let you generalise.
