Regardless of who the broadcaster is the presenters views should be restricted to appropriate channels. If they are reading the news, or presenting a football show, that would not be the place to spout personal political opinions. If they are being interviewed about their opinions, or their job is to give their opinions - like Portillo and Abbott on that show with Andrew Neill which was stupidly cancelled leading to his GB News fiasco - and it’s always clear that they are giving a personal opinion, that’s fine. Some people are there to have opinions for money - like Clarkson and Liddle in the papers. They are still employees.
Is ITN meant to be impartial too? Always seems it to me. Sky not sure, but the credibility of a news channel must to some extent depend on at least an attempt at objectivity/balance. Where this isn’t the case - Fox in the US, GB News and Channel 4 news here - you just have an echo chamber largely viewed by people who want to hear their own opinions shouted back at them so they can agree the **** out of it.
If the broadcaster has rules about use of social media (don’t know if the BBC has) then the presenter would have to decide whether they are happy to follow the rules or resign. The company I used to work for was very clear on this. Use social media as you wish, including for political reasons, but don’t discuss our products or our competitors, and, of course, don’t engage in illegal stuff, incitement to violence, racist comments etc.
Not in response to your question, but it’s just occurred to me that Lineker and his colleagues were allowed, probably encouraged, to talk about and highlight human rights issues in Qatar while working for the BBC during the World Cup. Yet he is castigated for using a personal platform to comment on human rights in his own country? Smacks of Stainsey’s favourite word….hypocrisy.
Football Focus and Final Score dropped as no one is prepared to present them. Sadly this is overtaking discussion and debate around the immigration policy itself. Braverman must be delighted.
