The UK government had earlier this year ordered an inquiry into a so-called Trojan Horse plot by Islamist extremists to infiltrate schools in Birmingham, which has a large Muslim population -- nearly 22 per cent.
Government sources have said that officials at the UK's Department for Education (DfE) are concerned that the situation may be worse than that uncovered in the Trojan Horse scandal.
"Tower Hamlets is expected to be the next Birmingham, but even worse, because the problems surrounding Muslim fundamentalists imposing their views on education seem to be more embedded," a source said.
Both secular state schools and private Islamic schools are under suspicion, and there are concerns that non-Muslim teachers are staying silent for fear of losing their jobs.

The prospect of a new Trojan Horse-style scandal in Tower Hamlets will alarm ministers.
The original plot, first revealed by The Sunday Times, resulted in the removal of several head teachers and boards of governors in Birmingham.
A report into the scandal by Peter Clarke, a former head of counter-terrorism at Scotland Yard, found evidence of a "sustained" attempt to impose hardline Muslim views, with female staff bullied and Christian assemblies scrapped.
