BritBox bosses have slapped ''Allo 'Allo!' with a content warning.

The streaming service features an alert on all nine series of the classic sitcom, which was set during the Germany's occupation of France during World War Two and starred Gordan Kaye as French café owner Renee.

The warning reads: "This classic comedy contains language and attitudes of the time that may offend some viewers.”

When it first aired, the comedy was originally shown on BBC One in a teatime slot from 1982 to 1992.

An insider told the Daily Star newspaper's Hot TV column: "Bosses are worried the pantomime-esque sexual innuendo and the stereotyping of French and German characters could cause offence in today’s ‘woke’ world.”

The likes of 'Coronation Street', 'Fawlty Towers', the 'Carry On' films and 'Call The Midwife' also feature content warnings on the platform.

A spokesman for BritBox said of the labels: "Programming on the service that contains potentially sensitive language or attitudes of their era has carried appropriate warnings since our launch in November 2019, to ensure the right guidance is in place for viewers who are choosing to watch on demand.”

'Spitting Image' and 'Blackadder' producer John Lloyd recently insisted people have "lost their sense of humour" and taken away the chance of "nuance".

He said: "Over the last few years all nuance has been removed.

"You’re either with us or a Nazi. And it works both ways. People seem to have failed to see the other side’s point of view. And, to some extent, lost their sense of humour. They are angry, rather than funny.”

And while comedian Barry Cryer has defended classic sitcoms and insisted critics have misinterpreted the target of some jokes, he acknowledged there are some issues and suggested content warnings in June 2019.

He said at the time: "I don't think the BBC and other broadcasters should be cautious about repeating the shows from British comedy's golden age.

"Why not let the current generation see them? They might be horrified, but we should let them make up their own minds, then debate the issues.

"If deemed necessary, they could even screen them with a so-called 'trigger warning' about the themes they address and language used. So if anyone complained they could say: 'Well, you were warned.' "
