Just to add to my previous post @Vivienesarches689
What’s not clear is why Harry is dissatisfied with the current arrangement of bespoke security for each visit. It can’t be to do with safety, as the level of threat is assessed each time.
Could be:
he doubts RAVEC’s competence at assessing threat and thinks he knows better
he thinks he’s at greater risk than he actually is, because he doesn’t have access to the relevant intelligence, nor the ability / experience to interpret it
he doesn’t feel he should have to give notice and would prefer armed police on standby just in case he turns up
he sees himself as equal in importance to William, so feels he should have whatever William gets
he wants security at all times (which he could have if he provided his own) but doesn’t want to pay for it
he thinks that if he’s judged to need 24/7 armed security here, other governments might also oblige, which would save him loads of money
he sees armed security as an important status symbol
he promised Meghan he would sort it
he wants to bring the children over but she won’t allow that without all the bells and whistles
he has made such a hoo hah about the UK being unsafe and the bespoke arrangement insufficient, if he accepted it now, he’d look like a right wally
he thinks 24/7 security looks very royal (although it doesn’t really, as hardly any of them get it and it tends to be discreet when they do) and he needs to keep up that royal image
he thinks his father could sort it (which he can’t) and sees his failure to do so as a personal slight
despite leaving the UK and not being a working royal, he thinks the UK taxpayers owe him this for his life of service, which apparently began at birth
he finds it difficult to understand and accept the inevitable change in circumstances which came from his decision to step down as a working royal and move overseas
There may be another explanation of course! Hopefully posters will add if I have forgotten anything.
