A religious education teacher has been struck off, after they were investigated for posting Islamophobic comments on social media and attending a march organised by the far- right group Britain First.

Nicholas Hall, a teacher at a comprehensive school in Leicester, admitted he had attended a Britain First marches on more than one occasion, and admitted to posting the intolerant messages online, The Guardian reports.

Hall also admitted to other serious matters including allowing 12- and 13-year-old pupils to watch an 18-certificate film, accessing pornography on a school laptop, failing to take appropriate action when a pupil acknowledged taking drugs, and working as a security guard while on sick leave.

The professional conduct panel which recently reported its conclusion, said Hall was guilty of “unacceptable professional conduct” and “conduct which may bring the profession into disrepute”.

It also concluded that he had breached his responsibility not to undermine “fundamental British values, including democracy, the rule of law … and tolerance of those with different faiths and beliefs”, and that his conduct had violated the rights of his students.

Hall is reportedly the first teacher to be struck off because of his association with Britain First, which was formed three years ago by a former of former British National Party members.

Comments he made on social media included “What a sick religion Islam is” and “We will leave them alone when the plague of Islam is [eradicated] from our planet.”

Hall has been banned indefinitely from teaching in any school, sixth-form college or other children’s establishment in England by the professional conduct panel. He has a right of appeal to the High Court.

53 year old Hall had been teaching at Soar Valley College since 2001. The panel concluded there was sufficient evidence that he had attended numerous rightwing events and he had shown “vehement intolerance” towards people of other religions.

The panel said Hall had yet to express any remorse for his actions.

In its report, the professional conduct panel also said:

“The panel believes that such an attitude is completely incongruous with Mr Hall’s role as a teacher, but particularly his role as an RE teacher of the college.”

Hall said he had no comment to make other than that he had “moved on” since losing his job, following the decision.
