THOUSANDS of school heads in England are suffering mental health problems, sleepless nights – and many may quit due to health fears, a damning survey found yesterday.

The study by the National Association of Head Teachers (NAHT) painted a “bleak picture of the unacceptable toll school leadership is taking on our members and their mental health and wellbeing,” the union said.

It blamed the government’s education watchdog Ofsted for widespread mental health issues among head teachers.
