Guto Harri has quit GB News following a row over him taking the knee during a debate on the racism directed towards England football players, it has been reported.
According to the BBC, the journalist and former advisor to British Prime Minister Boris Johnson decided to leave the channel after he was suspended following a viewer backlash over his actions.
Last week, GB News apologised after Mr Harri made the gesture on air in response to the abuse suffered by members of the English football team following their loss to Italy in the Euro 2020 final.
The statement said: "GB News stands four square against racism in all its forms. We do not have a company line on taking the knee.
"Some of our guests have been in favour, some against. All are anti-racist. We have editorial standards that all GB News journalists uphold.
"On Tuesday a contributing presenter took the knee live on air and this was an unacceptable breach of our standards.
"We let both sides of the argument down by oversimplifying a very complex issue."
Writing in the Sunday Times, Mr Harri previously said: "I joined, part-time but with an ongoing commitment, because I liked and trusted those in charge and supported the broad vision.
"But the channel is rapidly becoming an absurd parody of what it proclaimed to be.
"Rather than defending free speech and confronting cancel culture, it has set out to replicate it on the far right."
On Saturday, it was announced that Nigel Farage would present a daily show on GB News.
The former Ukip and Reform UK leader said he "will not be taking the knee for anyone on this show" in a video announcing the news.
