The UK Home Office confirmed on Wednesday that head of the Islamic Movement's northern branch, Raed Salah, was been detained by the UK Border Agency and is set to be deported.
The Islamist leader was set to address an event in the UK Parliament on Wednesday, organized Labor party MPs, and pro-Palestinian activists, Jeremy Corbyn and Richard Burden together with the anti-Israel fringe group Palestine Solidarity Campaign.
UK Home Office Minister Theresa May said that arrangements were now being made to deport Salah from the UK.
"We do not normally comment on individual cases but in this case I think it is important to do so. Salah’s presence in the UK has caused controversy. The Home Office had excluded him for his anti-Semitic views yet he was able to enter the country on Saturday unchallenged.
"I can confirm he was excluded and that he managed to enter the UK. He has now been detained and the UK Border Agency is now making arrangements to remove him," May said.
"A full investigation is now taking place into how he was able to enter."
