The National Union of Teachers is accused of supporting an event where a series of speakers, including a banned school governor, are expected to defend the Trojan Horse plot.

Kevin Courtney, the general secretary of the NUT, will appear alongside Tahir Alam, the former chair of governors at Park View school and alleged ringleader of the Trojan Horse plot who was accused of orchestrating a plan to promote Islamist religious teaching in schools.

Many of the speakers are expected to defend the actions of teachers who were found to have instilled an hard-line Muslim ethos in their schools. The event, named “Trojan Horse: the facts”, will suggest to parents that school leaders involved in the plot were in fact "discriminated" against and that the Muslim community was "stigmatised" in the wake of the scandal.

It will also explore whether the Trojan Horse plot led to "exam failure for a generation of children" - despite the fact that the school at the centre of the scandal markedly improved after a change of leadership was imposed.
