Personally I would not move to Leicester or Coventry.
Leicester is due to become the first city in the UK to have over 50% ethnic population (many of those from the Indian sub continent), which may not be a problem to you but would be to some.
See in Wiki that while 9% of the total UK population are foreign born, over 23% of the Leicester population are foreign born, with 30% of the population being Asian.
However according to Wiki a lot of Irish have also moved there so that may suit you.
I believe Leicester does a lot of work in its universities regarding the various space projects (Hubble etc) and they do have the Space Centre there.

Coventry is a city which, I am afraid, has passed its sell by date and is going nowhere.
It was once a very rich city (in the middle ages) and before the 2nd world war had some wonderful old churches and historic buildings.
But the Germans bombed most of that and it was re-developed during the 1960s to have a hideous concrete city centre. Much of the industry has gone (Peugeot, Jaguar cars etc) and anyone with any get-up-and-go leaves Covenry to live elsewhere.
There are plans to redeveop the city centre (again) but this has not started yet.
Very good university nearby, Warwick University (the university is actually in the suburbs of Coventry but they thought it sounded better to call it Warwick University.

Stand by for complaints about my append from people living in Leicester and Coventry.
