I think the Succession to the Crown Act needs to be updated so that a) members can request their removal from the line, and b) anyone on the line who has become so compromised they could never actually do the job if called upon can be removed by MPs. If there were a series of terrible accidents, Andrew for example could never seriously become King.
I think the removal of primogeniture also needs to be applied retrospectively not just Charlotte onwards.
No matter how unlikely it is that they should be called upon, I think it’s ridiculous that they still get the perks of being in the line of succession while destroying their own credibility to actually do that role. Perhaps we’d have gotten better behaviour from certain Dukes of York if they’d known there was a chance to lose their place.
