John McAndrew, head of programming at GB News, has reportedly quit the station amid a row involving presenter Guto Harri.
Harri - a weekend presenter - has reportedly been suspended from work after he took the knee live on air during a discussion about racism.
In a statement, GB News described the gesture as "an unacceptable breach of our standards", accusing Harri of "oversimplifying a very complex issue".
According to The Guardian, industry veteran McAndrew has now quit his role due to the furore.
McAndrew was a key figure in hiring most of GB News's on-air talent and is said to have left after coming under pressure to pivot the station towards more discussion of so-called 'culture war' topics.
The broadcaster has yet to confirm either McAndrew's departure or Harri's suspension.
