Social media exchanges between teachers at Park View School in Birmingham show an "intolerant Islamist approach", according to a Government report into the alleged 'Trojan Horse' plot.
The report's author, Peter Clarke, says the discussions on the WhatsApp messaging site give a "clear and disturbing insight" into the attitudes of some of the teachers at the school.
Among the topics discussed were Lee Rigby's murder, the Boston Marathon bombings, segregation in schools, along with what Clarke calls "explicit homophobia".
Clarke also said there was a "a constant undercurrent of anti-Western, anti-American and anti-Israeli sentiment" in the postings.
