One hundred Muslim women who wear a burka or niqab have written to Tory chairman Brandon Lewis to demand Boris Johnson be thrown out of the Conservative Party. I would go further and say that it is absolutely ridiculous that people should choose to go around looking like letter boxes'.
If Mr Johnson's comments are found to have breached the party code of conduct, he may face a string of punitive measures.
"We live in a land that has freedom of expression, freedom of speech, freedom of worship and freedom of choice and if you want to uphold those there will always be those that take offence", Duncan Smith told the BBC Radio 4 Today programme.
Critics claim Johnson is using the burqa comments to boost his appeal among right-wing members of the party.
Arguing in favour of free speech, Mr Mitchell suggested we may as well shut down every single national newspaper if we wanted to stop people from being offended.
He added: "All jokes about religion cause offence, so it's pointless apologising for them".
'You should really only apologise for a bad joke.
But Muslim organisations said there had been "a real impact" from Johnson's remarks. "On that basis, no apology is required", he added. "I fear an eruption of anger amongst our party's core voters and grassroots activities if this obsessive political correctness doesn't stop".
The ex Foreign Secretary faces being punished by party bosses and could even be kicked out of the party over the remarks, although this is very unlikely.
And they were joined by Blackadder star Rowan Atkinson, who said: 'As a lifelong beneficiary of the freedom to make jokes about religion, I do think that Boris Johnson's joke about wearers of the burka resembling letterboxes is a pretty good one'.
While fellow Tory MPs have called on Johnson to apologise.
