According to the Express Tribune newspaper, the decision was apparently taken in a high level meeting with Britain's home secretary Theresa May who decided that Bilour's presence in the UK would not be "conducive to the public good".
Along with Bilour, the anti-Islam filmmaker Nakoula Basseley Nakoula has also been banned from entering the UK. Both have been declared "undesirable" as their presence in Britain could harm race relations and pose threats to Britain's national interests.
Days after violent protests broke out across the Muslim world over the anti-Islam film, Innocence of Muslims, Bilour had announced the reward for anyone who could kill Nakoula. Bilour had urged the rich people of the world to donate so that any prospecting killer could be "loaded with dollars and gold".
