Fears of a new “Trojan Horse” Islamic plot to take over a state school in Oldham have been raised by its head teacher, who says she has been concerned for her personal safety.

Trish O’Donnell, head of Clarksfield Primary School since 2006, has been so worried that she has worked from home for short periods in recent months.

In an email sent to Oldham council in December, O’Donnell said she had “very strong reasons to believe that . . . a ‘Trojan Horse’ agenda [is] being played out” and that her position was becoming untenable.

The head teachers’ union, the NAHT, said it was “supporting a number of members in the Oldham area with a variety of apparent Trojan Horse issues”.
