Hawzah News Agency - The Muslim Council of Britain - which represents more than 500 mosques and charities - said the party appeared to have turned a "blind eye" to discrimination against followers of the faith.

The group renewed its criticism of the Tories on Tuesday as it backed an intervention from the Chief Rabbi over Labour's handling of anti-semitism.

Writing in The Times, Rabbi Ephraim Mirvis had said Jews had "been treated by many as an irritant, as opposed to a minority community with genuine concerns" for questioning Labour's stance on anti-Jewish abuse.

And he suggested Jeremy Corbyn was "unfit for high office" because of the party's response.

While he stopped short of urging a vote against Labour, he called for everyone in Britain to "vote with their conscience" in the upcoming general election.

In its own statement, the MCB said: "Today's statement by the Chief Rabbi highlights the real fear many British Jews have, regarding the unacceptable presence of anti-semitism in Britain and in politics today.

"Racism wherever it comes from - whether from the left or the right - is unacceptable, and not enough is being done. We agree with the Chief Rabbi's observation that some politicians have shown courage but too many have sat silent.

But the MCB also trained its fire on the Tories, who have faced criticism after appearing to water down a promised inquiry into anti-Muslim abuse, and sparked outrage with Boris Johnson's own description of women wearing the veil as "letterboxes" in a newspaper column.

A string of members have meanwhile been suspended from the party in recent months over anti-Muslim comments posted online.
