Prior to the current government the Tories were in power for 14 years, mostly with a majority. So I guess your opinion that the elites are left wing must be quite recently formed?
For the newspaper editors, take a look at the circulation figures for 2020 (the last year that we have a full set)[1]
The Guardian, i, and Mirror had a combined circulation of 800,989.
The Mail, Express, Sun, Times, and Telegraph had a combined circulation of 4,246,217. That’s 81% (you'll also notice there are more of them). The newspaper landscape in the UK is overwhelmingly right wing.
I don’t know why you’ve included Civil Servants, since according to your own data only 32% of respondents think they’re part of the elite.
I think this has probably run its course. I did ask for evidence, but from your answers for CEOs and bankers it’s pretty obvious that your opinion is just based on vibes.
You picked the sample, not me. Those categories are taken directly from the YouGov poll that you linked. I took the four categories where "Are members of the ruling class" scored higher than "Are not..."
Your own data doesn't support your argument. I'd also point out that the comment you originally replied to specified "economic/political elite", which is why I started off with politicians. The BBC doesn't fall into either category, it's media.
CEOs - quite a large proportion.
Bankers - more than you would expect
Newspaper editors - Guardian, Mirror, Independen
Civil Service - pretty much all of it
