Religious extremists are still infiltrating British schools in the same way as happened in the Trojan Horse scandal in Birmingham, MPs have been warned.

Government integration tsar Dame Louise Casey published a major review on community integration across Britain last month, revealing a shocking picture of 'ghettos' in some British towns.

Her investigation found segregation and social exclusion are at 'worrying levels' and are fuelling inequality in some areas of Britain.

In evidence to the communities committee, Dame Louise today told MPs it had been 'easy' during her probe to find troubling examples in schools.

She said many bore a resemblance to the Birmingham Trojan Horse scandal where Islamists infiltrated and took over three schools.

Dame Louise told MPs today: 'Yes, it is happening elsewhere.'

She added: 'In terms of some of the things seen in what's called the Trojan Horse, we did not find it very difficult to find things like segregation of girls, what I would describe as anti-equal opportunities or anti-liberal values.'

The veteran civil servant warned MPs that headteachers were on the 'front line' of policing the influence of community leaders on schools.

DAME LOUISE CASEY'S REVIEW: AT A GLANCE Dame Louise Casey published her major review into integration in Britain in December. It found: Communities say the pace of change because of immigration has been 'too much' for them to deal with

There is 'nowhere near' enough integration in communities given the 'pace and scale' of population change

Some communities are becoming more segregated and Britain is facing 'escalating division and tensions in society'

Much more effort is needed to ensure integration and 'bind Britain together'

Migrants should sign up to an 'oath of integration with British values and society' as soon as they arrive or even before

Children should be taught British values of tolerance, democracy and respect as well as British laws and history

Women in some communities are being 'held back by regressive cultural practices' and face coercion, violence and abuse in the name of 'cultural or religious values'

Children being taught at home are being exposed to 'divisive practices'

Ministers should provide more English language classes for 'isolated groups'

All councillors, MPs and other public office holders should swear an 'oath of integration enshrining British values'. Advertisement

Dame Louise said it meant deciding in secular schools the extent to which religious requests were 'reasonable' and which would cause harm.

She said: 'Should a secular school close at 1pm on a Friday for religious reasons?

'I know what my view is on that but I know that headteacher has to have a very difficult set of conversations with ''the community'' which often turns out not to be the parents.

'Again, that is not everywhere in every bit of the country but it is in some communities in some areas. We found it.'

Dame Louise said in some parts of the country public officials did not take the threat seriously and even believed the Birmingham scandal to be a hoax.

She warned: 'Now, Trojan Horse is a set of issues - they go from girls being split off from boys, through teachers essentially teaching extremism.

'I'm not sure I'm saying that end is everywhere but do I think some of the dynamics that happened in Trojan Horse are at play in other areas of the country, yes I do.

'More importantly when does a teacher running a secular school say it's fine for you not to do theatre or music or those sorts of things? When is that OK?

'I don't really have a view on which religion it is that's promoting those sorts of views but it is not OK, the same way it is not OK for Catholic schools to be homophobic and anti gay marriage.

'That's not how we bring children up in this country. It's often veiled as religious conservativism.

'I have a problem with the expression of religious conservatism because I think often it can be anti-equalities.'

One of the areas investigated by Dame Louise was the Page Hall area of Sheffield there is a 6,000-strong Roma or eastern European community living together (pictured)

Her bombshell report says ghettos have formed because the pace and scale of immigration has been 'too much' and some towns and cities like Bradford (pictured) have been transformed 'out of all recognition'

Dame Louise said there was a 'grey line' between talking about Islamic extremism and far right extremism.

She told the MPs: 'Everybody is frightened of being branded a racist - there are some nasty people on the right who clearly aren't - but most normal people are frightened of being branded a racist.

'The very genuine fear in all of this is we have two extremists alive in our communities. We do have the extreme right wing which is milking all of this for its worth.

'We have extreme right wing in our country which we are all utterly appalled by.

'But we also have Islamist extremism at play and I have felt at points it has been easier to talk about one than it is to talk about the other.
