How do you say Manchester in french?

J'habite à London en Angleterre...

J'habite is I live - to say "You live in" is "Tu Habite"

à London en Angleterre is "In London, In England"

Hope this helped - this was how I was taught it. I'm English by the way so I could be wrong to any native French speakers.

'J'habite à Londres'

Londres is French for London. Also, 'London England' is only ever said by people from the USA. Just plain 'London' (or 'Londres') is sufficient.
