If the Muslim Brotherhood takes power in Egypt, its first move could be to review the peace process with Israel.

Banned under President Hosni Mubarak, the Islamist group is understood to have the support of just a quarter of Egyptian voters, but is well-organised and has been vocal since anti-government protests erupted more than two weeks ago.

Jewish and Muslim leaders have called a demonstration planned for tomorrow by the English Defence League (EDL) an “inciteful event”.

A number of the EDL’s previous 30-odd rallies and protests have descended into violence and resulted in arrests.

At the first major debate on antisemitism last Thursday at Westminster Hall, John Mann, chair of the All Party Parliamentary Group against Antisemitism, said he was frustrated with progress on the issue.

MPs have pledged to crack down on antisemitic preachers on campus and internet hate sites during a major parliamentary debate on antisemitism.

An extremist American pastor who said Judaism was “of the devil” and threatened to burn a Koran on the anniversary of the September 11 attacks has been excluded from Britain.

A Home Office spokesman said the decision was because of “numerous comments” by Mr Jones that were “evidence of his unacceptable behaviour.”

Members of the interfaith Council of Imams and Rabbis had sent home secretary Theresa May letters appealing for her to stop Mr Jones entering Britain.
