A quote from The Daily Telegraph, 7 March 2009

Campaigners from the Centre for Social Cohesion have pledged to seek an arrest warrant for Dr Ibrahim Moussawi, an Islamic extremist, who is due to visit Britain this March. The think-tank said the Home Office would be "beyond hypocrisy" if it allowed Dr Ibrahim Moussawi into Britain just weeks after barring Geert Wilders, the Dutch politician, because of his alleged anti-Muslim views.

Dr Moussawi is a spokesman for the Lebanese-based militant group Hizbollah, the military arm of which is banned in Britain as a terrorist organisation. He has allegedly called Jews "a lesion on the forehead of history" and said of Israel: "Pain is the only language that the enemy understands."

Douglas Murray, director of the CSC, has written to Jacqui Smith, the Home Secretary, warning her that he will instruct lawyers to seek an arrest warrant for Dr Moussawi if he is allowed into the country.

The think-tank has already sought advice from barrister Paul Diamond, an expert in religious affairs law, on using war crimes legislation and a legal precedent from 2004 to seek, independently, an arrest warrant from a magistrate. […]

Dr Moussawi is due to address a conference at the University of London's School of Oriental and African Studies, on March 25, on the subject of political Islam. Senior civil servants and police officers are among those who will pay up to £1,890 to attend the event, which is intended to improve understanding of radicalism.

Dr Moussawi has been granted a visa to visit Britain at least twice in the last two years but it is understood that he has yet to apply for permission to re-enter. […] In its letter to Ms Smith, the Centre for Social Cohesion said: "[…] It is the position of the Home Office that individuals are banned from entry in the United Kingdom if 'they stir up tension and provoke violence to others'.

"Dr Moussawi would threaten community harmony and clearly breach this condition. If Dr Moussawi arrives in the UK we will instruct counsel to seek a warrant for his arrest." […]

Mr Wilders, 45, planned to show his controversial film which links the Koran to terrorism, but was banned from entering Britain because he was classed as someone likely to incite hatred and threaten "community harmony".
