The Birmingham academy trust at the centre of the so-called 'Trojan Horse' allegations was accused of running schools that took the Islamic focus too far. A highly-critical report found a classroom culture which was not welcoming to non-Muslim pupils. It described a ‘madrassa curriculum’ in personal, social, health and economic lessons, and ‘posters written in Quranic Arabic in most of the classrooms visited’. Loudspeakers were used to broadcast the call to prayer and there were posters in classrooms encouraging children to begin lessons with a Muslim prayer. There were also claims of an inappropriate external speaker being brought in to talk to pupils. In RE lessons, the few pupils taking a Christian unit in the GCSE course, rather than the Islamic Studies paper, had to ‘teach themselves’ because the teacher had to concentrate on what the majority were studying. As far back as 2010 the Department for Education was warned that Muslim hardliners were trying to take control of Birmingham schools. See: http://www.bbc.co.uk/news/uk-27476643
