"A culture of fear and intimidation has taken grip" in Birmingham schools caught up in the Trojan Horse claims, says Ofsted chief Sir Michael Wilshaw.
Head teachers have been "marginalised or forced out of their jobs", said Sir Michael, as he delivered his findings on claims of hardline Muslim takeovers.
The Ofsted chief said there was evidence of an "organised campaign to target certain schools".
Leaders of one of the schools, Park View, firmly rejected the claims.
The BBC's Gillian Hargreaves explained Ofsted's findings and its recommendations.
