A London primary school teacher was allegedly banned from working with children after telling a Muslim student that 'Britain is still a Christian state'.
The teacher, who chose to remain anonymous, was suspended and sacked after he reprimanded students for washing their feet in the sinks in the boys' toilets, it is reported.
Afterwards, he reminded the Year 6 class that Islam was a minority religion in the UK.
And according to the child who made the complaint, he said there was a Islamic school a mile away if they wished to attend it instead.
The educator was subsequently suspended and then sacked in March last year, The Telegraph.
A month later, he was referred to a local safeguarding board and The Metropolitan Police.
Allegedly, the safeguarding officer concluded that he made hurtful comments about Islam and that the child had been subject to emotional harm.
The police inquiry has since been dropped but the teacher is apparently suing the local authority with backing from the Free Speech Union.
It is understood the teacher has appealed the ban and is working part-time at another school outside of London.
Lord Young, the director of the Free Speech Union, said on Monday: 'This teacher lost his job and almost ended up being barred from the profession for life just because he pointed out to a class of Muslim schoolchildren that the national religion of England is Anglicanism.
'Things have reached a pretty pass in this country if a teacher can be branded a safeguarding risk because he says something that's incontestably true.
'If he'd claimed that Islam is the official religion of England, even though that's not true, I doubt he would have got into any trouble.'
It comes after an Iraq war veteran who was cleared of a 'hate crime' in 17 minutes was banned from coaching his daughter's football team after he complained about illegal immigrants.
Jamie Michael, from Penygraig in south Wales, was charged with inciting racial hatred following comments he made in a 12-minute Facebook video.
The 47-year-old described some migrants as 'scumbags' and 'psychopaths' as riots spread across the UK in the aftermath of the Southport murders.
Despite his acquittal Mr Michael was told a 'child protection concern' made against him had been 'substantiated' less than a fortnight after the jury delivered its not-guilty verdict.
As a result the Football Association of Wales has now barred the father-of-two from coaching his daughter's team following a meeting held in private with a safeguarding officer and South Wales Police.
The ruling has prompted concern from free speech campaigners who claim people with 'patriotic views' are being 'silenced' due to 'safeguarding concerns'.
The Free Speech Union (FSU) said it had identified more than a dozen cases of laws intended to keep children safe from adults being used to stamp out Right-wing views.
