I cant find anything that supports that statement.

They show GB News to be watched less than BBC News and Sky News (and dont take into account that most people watch prime time BBC News programmes (at 1pm, 6pm, and 10pm) on BBC1, which is simulcast with BBC News at those times. For instance, the 6pm News on BBC1 on Tuesday 12th September was watched by 3.5 million viewers, and on the Monday and Wednesday of that week, by 3.36 million viewers.
I dont believe any GB News programme has reached those figures.
