Harry talked of the relationship between the Palace and certain publications, how they were wooed, wined, dined and an air of you scratch my back and give me a story, and I'll do positive press. I can link you to what he said if you like, but as it's Harry you will discount it of course
I won’t discount that at all, Meghan rather confirmed in in her texts to JK - “if I like Omid’s book proposal I’ll invite him to a function he wants access to” was the gist of it. There’s always a quid pro quo.
Sometimes this works in the Royal family’s favour - Harry in Afghanistan is a good example. The press all co-operated and played dumb about his whereabouts, and it only came up because a US publication and New Idea in Australia weren’t in on the deal.
But I think the whole Royal family is very well aware that the press coverage can (and does) turn on a dime. The Sun’s senior editorial team have spoken openly about how Gordon Brown was supported as PM despite them thinking he really wasn’t up to the job, until one day in September 2009 they (ahem, Rupert Murdoch) just decided his time was up, and started to roll out hugely negative coverage of him and Labour. He and Labour were out the next election. Now, obviously we can’t vote the Queen out, but they also look for positive public opinion and so are at the mercy of the press.
I genuinely don’t think it’s the Royal family who has the power in this relationship.
