The members of the education trust at the centre of the alleged "Trojan Horse" takeover plot in Birmingham schools have resigned "with a deep sense of injustice and sadness."
Tahir Alam, of the Park View Educational Trust, made the announcement today outside the gates of Park View Academy in Alum Rock, Birmingham.
The allegations in an anonymous letter - now widely held to be a hoax - claim the existence of hardline Muslims attempting to seize control of Birmingham schools.
Those allegations triggered several inquiries and last month the trust's three schools were placed in special measures by Ofsted.
Mr Alam has always denied any wrongdoing and branded the investigations "a witch hunt".
