As I have said before, I worked with the BBC at national level between 2016-2019 as a regular paid contributor.

It is an establishment organisation, which means that, through its history, its news output has generally trended towards right of centre, even if many of us thought it was social democratic at points - and there were periods in 1945-79 when that was true as that was where the centre of political gravity was then.

Since 1979 it has increasingly moved to the right as the establishment has, but it has become structural now. The presence of senior Tories such as Robbie Gibb on the board, especially given his awful behaviour when Director of Comms in No 10, has fatally compromised the organisation.

Between 2016 and 2019 I saw first hand how the independence of even freelance contributors was reduced. Shortly before going on the week after Grenfell an assistant producer spoke to me and said I wasn't to mention May not meeting the families as 'Downing Street was unhappy'. This was when Gibb was there. He's now on the board of the BBC.

I later reported this and was promised the Impartiality Unit would carry out an investigation, but I heard no more about it. In the end I stopped contributing after I was due to appear in a news programme the week Kuennsberg doxxed a concerned father who had asked Boris Johnson difficult questions about the NHS during the election cycle, and not long after Johnson had illegally prorogued Parliament.

By this point, contributors such as myself who appeared on certain flagship news programmes (I was mostly on BBC Breakfast) were being given grids of what they should talk about, specifically in relation to newspaper stories. I ignored them but that was not sustainable in the long run.

I also used to appear regularly on Snelly's show locally doing the news review, but this was axed and I sense that BBC bosses didn't like these segments as there was little editorial control over them and they pissed off the government. Snelly is a great lad and was a pleasure to work with though, it was a privilege.

If you want a good account of the BBC's historic role at national level (ir's always been better locally) in covering for the establishment I'd recommend Tom Mills' booK The BBC: The myth of a public service.

TL;DR - to your point, the right are acting in bad faith as they usually do (it's their MO) and driving the organisation further right, as right-wing parties of various stripes (including this version of Labour) havw been power for decadss.

The left critique is then a valid one.

The formula you apply can be applied to more or less any issue, but if one side is arguing in bad faith then it fails. Take for example the 'free speech crisis' - this did not exist, but was manufactured by the right because they wanted to be able to be racist, sexist and transphobic again publicly, and wanted to use insitutional and legislative change to legitimate that.

The right never argued in good faith about 'free speech' or 'academic freedom'. Both sidesing it doesn't wash. The left were correct, but the BBC takes and platforms right-wing bullshit at face value, sadly.

Beyond that, the Beeb has a long track record of editing footage or framing stories in a way hostile to the left or favourable to the right; Orgreave, the Corbyn Communist Newsnight episode, Johnson at the Cenotaph, etc.
