Wary of making any comment on this, as such a sensitive and potentially invidious subject. But I know Leicester very well and there are socio-economic factors, as well as religious, driving these disturbances. It is a generalisation, but largely correct, that the Hindu and Sikh communities have integrated better than the Muslim ones and have been much more successful in migrating from the inner city to the more prosperous middle class suburbs and villages. The Hindu people have, on the whole, been there a generation longer than most of the Muslim community, but there is little sign of a parallel progression.
That said, the violence seems, according to people there, to have been initiated by BJP extremists, hence the protests from the Muslims.
