This does indeed seem to be what this person is saying. Thanks for putting in the effort to parse, though I do have to apologise for the fact that it hardly seems to have been worth it!
Meanwhile in the real world, Charles Moor, former editor of the Telegraph, is mooted to become the chairman of the BBC and Paul Dacre, former editor of the Daily Mail, is to be head of ofcom, the media regulator.

OK, very wrong, but I think that's attempting to describe the elected labour mps in parliament
"activist shills"
I assume this means people who don't read the daily express
So I think I can parse this as

I'm not sure what story he's talking about though.
