In 2014 the UK government launched an investigation into the “Trojan Horse” affair: an alleged plot to “Islamify” several state schools in Birmingham. Twenty-one schools in Birmingham were subjected to snap Ofsted inspections and included in the various inquiries into the affair. The book's authors — one who was an expert witness in the professional misconduct cases brought against the teachers in the school, and the other, who researches the government's counter-extremism agenda — challenge the accepted narrative, arguing that a major injustice was inflicted on the teachers, and they go on to show how the affair was used to criticize multiculturalism and justify the expansion of a broad and intrusive counter-extremism agenda. The government cites the 'plot' in its argument about the need to develop a new counter-extremism strategy that confronts extremist ideology and not just threats of violence. However, the Kershaw Report and some other commentators argue that there was, in fact, no evidence of extremism.
