Representatives from the Muslim and Pakistani communities in Derby have called for all trustees of the Al-Madinah free school to stand down.
Speaking today, they said the position of trustees has become "untenable".
It follows the sudden resignation of the chairman of governors Shazia Parveen this morning.
In a statement read out by another person, she said her departure was "in the best interests" of pupils.
A controversial Muslim free school in Derby has been branded 'dysfunctional' and 'in chaos' by Ofsted inspectors.
The Schools Minister has declared he is 'even more convinced' of the need for 'urgent action' to be taken at the Al Madinah free school.
