Another Birmingham school has been placed in special measures by Ofsted - with its head and governors likely to be removed - as fears grow of a resurgence of the "Trojan Horse" plot.
In a report to be published this month, Small Heath, a previously "outstanding" non-faith state secondary, will be downgraded to "inadequate", the lowest possible score.
Inspectors who visited 10 days ago found a "narrowing of the curriculum" and staff in turmoil after the previous - secular - head left.
Shanaz Khan, the new head teacher, who started in September, was heavily backed by several of the key plotters in Trojan Horse, which drove out non-Muslim head teachers and imposed hard-line Islamic practices at a number of state schools in Birmingham.
Mrs Khan was previously deputy head of Cathays High School in Cardiff, the alma mater of Reyaad Khan and Nasser Muthana, the British jihadis in an Isil propaganda video, revealed last summer.

As The Telegraph revealed, extremist preachers from a mosque accused of radicalising the two men were welcomed to Cathays High to give regular classes. The sessions, entitled "Reminding Cathays High", included teaching the children that music and "free mixing", contact between boys and girls, was "not permitted in Islam".
Small Heath, the pupils of which are largely Muslim, was one of 21 Birmingham schools inspected last spring.
Under its then head teacher, Peter Slough, it was given the all-clear and judged "outstanding", the highest grade, a rating it had held for many years.
However, Mr Slough stepped down in July, saying he was "not retiring" but wanted to do something else. Asked whether he had been forced out, he laughed and said: "I've been here for 19 years, and before I get to the point that I can't contribute to education, I want to do something else.
"I'm looking forward to the next stage of my career."
In private messages on the WhatsApp discussion group, leaked to this newspaper, members of the plot - including Samir Rauf, then a Small Heath governor - celebrated Mrs Khan's appointment and discussed how she could pursue an "Islamising agenda".
"Great news," wrote Mr Rauf. "Was a hard battle... but the dynamics have finally changed."
One of the key figures in the plot, Razwan Faraz, who has been suspended from teaching for his role in the affair, wrote that Mrs Khan was "a very astute lady. She knows her game, God willing. Please don't pressurise her to start the Islamising agenda first, that will be a lot easier when she is respected as a leader".
Mr Rauf wrote: "My exact words to her, Razwan. However, at macro governor level, the ball needs to start rolling."
Mr Faraz then stated: "She has to establish herself with minimum controversy for the first six months and lead the people [staff] to believe in her before they believe in her policies... At the same time, she can't be a coconut [white on the inside]."
However, Mrs Khan appears to have alienated many staff. At least four senior teachers, including Tim Smith, the assistant head and head of sixth form, have resigned in recent weeks.
In a letter of Dec 18, to the chairman of governors, Jamshed Khan, circulated to staff and seen by The Telegraph, Mr Smith said he felt "angry and let down by the governing body", who had dismissively rejected the "concerns and misgivings" by senior staff about Mrs Khan.
He added: "To misquote Oscar Wilde, to lose one member of the leadership team may be regarded as a misfortune, to lose two looks like carelessness, but to lose four...?"
Another former member of staff said: "Ofsted received information from a former inspector, David Driscoll, who has been helping the school. What he saw and heard horrified him. Staff were very unhappy, standards were slipping, and members of staff who had served the school fantastically well for years were being ripped into at every opportunity."
A person familiar with the report of the Ofsted inspection, which was carried out at 10 minutes' notice the week before last, said it had found a "narrowing of the curriculum". Two other schools received clean bills of health.
Around 100 staff attended a special meeting on Thursday night to discuss the crisis, a teacher there said.
A proposed vote of no confidence in the governors and management was not taken but Mr Khan, the chairman of governors, resigned, staff said.
Mrs Khan is not related to him. However, some staff said she was related by marriage to another governor.
The special measures mean that she and the other governors are also likely to lose their jobs.
A report on the Trojan Horse affair, by Peter Clarke, a former police chief, found a "co-ordinated, deliberate and sustained action" to "introduce an intolerant and aggressive Islamist ethos".
Last week, Sir Michael Wilshaw, the head of Ofsted, told MPs that "very limited progress" had been made in protecting children from extremists, and warned those behind the plot could return.
Birmingham city council and a spokesman for Mrs Khan confirmed an inspection had been held but declined to discuss the results.
