A Government-ordered inquiry into the Trojan Horse allegations is expected to say that there was a "sustained and co-ordinated agenda" to impose hardline Muslim views in some Birmingham schools when it reports back today.

The investigation, led by former anti-terror chief Peter Clarke, was commissioned by former education secretary Michael Gove in April to investigate the alleged plot by a group of hardline Muslims to take over schools in the city.

According to the Guardian newspaper, which obtained a leaked draft of the report, Mr Clarke, who served as head of the Metropolitan Police's counter-terrorism unit, concludes there was a ''sustained, co-ordinated agenda to impose segregationist attitudes and practices of a hardline, politicised strain of Sunni Islam''.

The report is said to conclude: ''The agenda, but not the tactics, involved stem from an international movement to increase the role of Islam in education.''

It states: ''Left unchecked, it would confine schoolchildren within an intolerant, inward-looking monoculture that would severely inhibit their participation in the life of modern Britain.''

The conclusions are also expected to be heavily critical of Birmingham City Council, suggesting that the authority failed to support teachers and governors.

Education Secretary Nicky Morgan is expected to make a statement to MPs, setting out how the Government intends to respond to the Clarke report and Ian Kershaw's inquiry for Birmingham City Council, which was published last week.

Mr Clarke's report is last of four separate probes into the allegations in Birmingham, which were originally sparked by the "Trojan Horse" letter - now widely believed to be a hoax - which referred to an alleged plot by hardline Muslims to seize control of a number of school governing boards in Birmingham.

His findings are expected to differ to those contained Mr Kershaw's report, which concluded there was no evidence of a "conspiracy to promote an anti-British agenda, violent extremism or radicalisation in schools in east Birmingham".

Mr Kershaw's inquiry concluded that key individuals were ''promoting and encouraging certain Islamic principles'' in Birmingham classrooms amid poor oversight from education chiefs.

Last month,Ofsted issued a damning verdict on the running of a number of Birmingham's schools as it declared five failing and placed them into special measures.

The watchdog inspected 21 schools in the city, concluding that a "culture of fear and intimidation" has developed in some schools and, in several, governors exerted "inappropriate influence" over how they are being run.

In an advice note to Mr Gove outlining Ofsted's findings, chief inspector Sir Michael Wilshaw warned that Birmingham City Council had failed to support a number of schools in the area in their efforts to protect pupils from the "risks of radicalisation and extremism".

He also revealed that some headteachers told inspectors there had been an organised campaign to target certain schools in the city to change their "character and ethos".

The five placed in special measures as a result of the recent inspections are Golden Hillock School, Nansen Primary School and Park View Academy - all run by the Park View Educational Trust (PVET), as well as Oldknow Academy and Saltley School. A sixth - Alston Primary - was already in special measures.

The Education Funding Agency has also conducted its own inquiry, publishing highly critical reports on PVET and Oldknow Academy.

In his note, Sir Michael said that some headteachers revealed that they had been marginalised or forced out of their jobs. Many school staff were frightened of expressing views that went against those that were promoted by their school's governors. In one case, a school leader was so worried about talking to inspectors that they had to arrange a meeting in a supermarket car park.

Mr Gove came under heavy fire for his decision to appoint Mr Clarke to lead the DfE ordered investigation, with one senior police officer saying it is a ''desperately unfortunate appointment'' that will be misinterpreted by some people.

The DfE has insisted it is confident that Mr Clarke's background makes him the right man for the job.
