“Polls demonstrate significant scepticism across British society about the integration, and even the shared allegiance, of their British Muslim fellow citizens,” said Mr Grieve, who is a Conservative MP for Beaconsfield.

He said that Muslims face “considerable challenges” from within their own communities that prevent them from participating in public life.

“The Commission has also heard, forcefully expressed to it, the fear of many Muslims that, even in seeking to participate in public life or to work on a cross-community basis, they become subject to a much greater degree of adverse scrutiny, or to allegations about their motivation, than would be considered normal or acceptable for their non-Muslim counterparts,” Mr Grieve wrote. “This is a matter for which there is overwhelming evidence.”

The report found that the “increasing absence” of Muslims from British civil society is a “growing problem” in the UK.

It said that while in some areas Muslims are not participating in public life to their full potential, in other areas they are just as engaged, if not more,than their white British counterparts.

The lack of integration was most pronounced in areas of high deprivation, the report found, but added that there was a “wealth of positive community work” by British Muslims at a local level.
