Michael White taught at Park View School for more than 20 years before he was dismissed
A former teacher at a Birmingham school alleged to be part of an "Islamic takeover plot" says concerns were first raised more than 20 years ago.
Michael White, who was dismissed in 2003 from Park View School, in Alum Rock, said its board of governors was "taken over by a Muslim sect" in 1993.
He said he told the local education authority (LEA) but his claims were not investigated.
Tahir Alam, chair of governors at Park View, denied Mr White's claims.'Forced out' Birmingham City Council said it was unable to comment on historic or current allegations while investigations were ongoing.
Mr White said Park View's board of governors was reorganised after the school was put into special measures by Ofsted in 1993.
He said there was an increase in female students covering their hair within months of Mr Alam's appointment.
"The LEA was well aware of what was going on," he said.
"They told me they didn't want to exchange one set of problems for another."
Mr White said he was "forced out" after he challenged governors' attempts to ban sex education and stop the teaching of non-Islamic faiths in religious education classes.
In 2003 he was dismissed for gross misconduct after he handed a letter to prospective teachers advising them to question the governors
