Regional TV talent Jemma Cooper is best known for her regular appearances on Bristol’s Points West programme.
But it is alleged she put in a Covid-denial group the BBC was ‘the devil’ and appears to be in footage of an anti-lockdown march, where Piers Corbyn appears.
Today the broadcaster was forced to restate impartiality guidelines had to be strictly followed and any breach would be dealt with.

The insider said: ‘Jemma had arguments with colleagues who felt she was putting people in danger by going out to these events.

Who is Jemma Cooper?
Miss Cooper grew up in Portishead and joined the BBC back in 1999.
In 2000 she started working for BBC Bristol on their regional website.
But then joined live news to become a weather presenter.
In her heyday she worked on television breakfast and weekend forecasts as well as for the radio.
On a now-archived BBC profile page, she said: ‘Journalism is in my blood and I am confident about telling the weather story every day but weather is a science and I have put a lot of effort in to learn as much as I can about it.’
‘It has become a thing in the newsroom which we call “Where’s Wally”.
‘People find Twitter videos of lockdown protests and look for Jemma.’
The broadcaster has said Ms Cooper is still employed by the channel.
She has been off air for three months, but it said to have been helping with news stories.
Youtube footage she is said to appear in, shows a woman matching her likeness nodding at Corbyn.
An email sent to staff at Points West on November 5 said the presenter would not be coming in until they were advised differently.
It read: ‘Dear all, I want to let you know that Jemma Cooper has had to be called away from the office unexpectedly until further notice.’
Last month it was said that she confirmed her identity in an anti-lockdown group called Stand Up Bristol.
She replied: ‘Yes alas I work for the devil at the moment.
‘I joined the corporation in 1999 when I was 28 and fully asleep. Comatose.’
