I get the impression that Harry expected (a) the King, and (b) senior politicians like Yvette Cooper, to intervene directly in the independent RAVEC process.
More fool them if they indicated to him that they would or could. The most they could ever ask for on Harry’s behalf would be that a fresh pair of eyes scrutinise the process and the data points used; but, as @Thedom says, a High Court judge (or two?) has done this already.
I don’t understand the ‘pause’ comment from the Sussex PR machine either. (Has anyone else said it?) These risk assessments are rolling processes, always. They are continuous, as information comes into the big machinery of state security and protection and is collated, sifted, analysed, and acted upon appropriately and proportionately according to statute and regulations. Where there have been failings (‘Spy Cops’) there are public debates, inquiries and consequences, as is expected in a democratic country with a constitutional monarchy.
Harry is finally coming across as the spoiled brat he is, not the social justice warrior he wants to be perceived as. And he’s taking people down with him whose privilege is also now being questioned.
