"I think something will be done. Harry simply cant be allowed to go mouthing off for the next fifty years about how awful the royal family is. While retaining his place in the succession. Look what happened to Ratner."
It's not that simple.
Removing H from the line of succession requirements an act of Parliament. It's not something HMQ can do independently.
It's also worthy of note that H is all that separates Andrew from the throne if the Cambridge line is thwarted.
Despite the negativity towards the Sussexes I very much doubt if given the choice the public would prefer to see that odious bastard Andrew as King rather than Harry.
So if you did want to remove H from the line of succession I can't see how that would be possible without also removing Andrew - thus leaving the Wessex family as the direct heirs (there's also then a whole other question about if Anne's position should be re-assessed in favour of Edward but that opens up other legislative requirements making the situation even more complex).
There's no way the RF will want to do this.
Firstly, removing one person from the succession isn't great PR but removing two...it also then further ignites/highlights the Andrew shit show.
However, that's not really the biggest reason not to do it.
As soon as the RF asks parliament to remove either H or H&A they they lose control of the narrative.
Given the current Tory Govt I don't doubt any such legislation from a predominantly pro-monarchy govt with a large majority would pass.
However it would still have to be debated in the Commons and there is nothing stopping any of the Republican MP's (of which there are quite a few in the Labour Party/SNP etc) tabling motions to say well if we are getting rid of H&A then let's amend the bill to get rid of the lot.
Worse they get the opportunity in Parliament to discuss why that should happen - potentially listing every scandal etc into the public domain and thus framing a national debate on the monarchy as a whole.
They'd lose even if they win - so no, this isn't a route the RF will go down.
I don't think they will strip their titles either - as I posted in a other thread they can't "de-Prince" Harry (a title by birthright) and for the same reason, when Charles becomes King he can't stop Archie and Lili becoming Prince/Princess. HMQ would have to do this via Letters Patent before they inherit the titles and I just can't see that happening.
It's one thing to issue new LP's to prevent a first born female Cambridge child having a lesser title than a younger male sibling and as happened with a male heir, their siblings not having equivalent titles within that family it (as Archie and Lili are equivalent to each other) but quite another to actively prevent Harry's children inheriting their birthright.
Charles could only remove Archie/Lilly's titles by an Act of Parliament and the fallout of that is not dissimilar to that described above re: the succession. Again I just can't see him doing that (on the other hand I can see him issuing LP's to slim down the monarchy so that Charlotte/Louis's children are not entitled to be Princess/Prince and also asking H&M not to style their children Prince/Princess - but ultimately that's for the children themselves to decide upon adulthood whatever their parents views on the matter).
Far, far better to leave things as they are, because simply put H&M's revelations have been as damning to them as the RF in terms of popularity and fundamentally they are going to run out of things to say.
I think it's fair to say that the "bigger" brand of the RF is better placed in the long term to weather the storm of any further revelations from H&M (perhaps unless they have something "nuclear" to offer - but that's very risky to them. Anything big enough to really destabilise the monarchy would take their "status" away with it).
The whole situation with titles/succession is far more complicated that people realise and there's been muddying of the waters from a lot of sources.
Fundamentally in the OW interview M referred to protocol being changed for Archie and I think people have assumed that means Charles "stopping" Archie/Lili be Prince/Princess.
The fact is protocol has not been changed and Charles cannot prevent them gaining these titles.
What I think M actually meant was that she and H were operating under the presumption that the "protocol" ie LP's that were changed to ensure Charlotte and Louis were known as Prince/Princess from birth would happen again for their children and were upset when informed that was not the case.
It's therefore a matter of opinion as to whether you think it's reasonable that younger Cambridge children's titles were "accelerated" whereas this was presumably refused for the Sussex children and not a case of titles being prevented/removed as some people have wrongly interpreted.
