Hawzah News Agency (London, UK) - Britain's largest Muslim organisation has condemned the Conservatives over "fundamental failures" in addressing Islamophobia within the party's ranks.

In alarming remarks, the spokesperson for the Muslim Council of Britain (MCB) said he had documented "hundreds of cases" showing the scale of Islamophobia in Tory quarters.

It comes after the MCB submitted more than 20 pages of evidence to the Equality and Human Rights Commission, urging investigators to launch an official probe into accusations within the party.

Appearing at an inquiry of the Home Affairs Select Committee in Westminster into the definition of Islamophobia, Miqdaad Versi vented frustration at inaction and "unequivocal failures".

MPs also heard criticism of Boris Johnson, the ex-foreign secretary who is currently the frontrunner in the Conservative leadership race, after he compared women wearing niqabs to "letterboxes" in a column last year.

Addressing the committee on Tuesday, Mr Versi said: "We have seen unequivocal failures - specifically the Conservative Party when it comes to Islamophobia. Not just small failures, fundamental failures in every single way. I'm talking about leadership within the party, for example the mayoral election.

"I'm talking about issues when Members of Parliament have done certain things and no action has been taken against them. I'm talking about when councillors and representatives of the Conservative Party have said or done things which are inappropriate or unacceptable.

"Sometimes you've had action taken against them, and sometimes no action taken unless and until the media have been called at which point action has been done.

He continued: "And then what happens? A few weeks later they are quietly let back into the party. These type of things are unacceptable.
