Meanwhile, Middleton, 42, the sister of Catherine, Princess of Wales, 44, and Matthews, 50, have been permitted to enhance security at Barton Court, their $22.5million estate in Berkshire, England, where they live with their three children.
The development has prompted comparisons with Harry’s unsuccessful legal efforts to secure taxpayer-funded police protection during visits to the UK.
A source told us: “From a legal and administrative standpoint, the two situations are entirely separate, but that hasn’t stopped people from drawing comparisons. Any time questions of security, public funding and members of the royal family intersect, the debate quickly becomes emotional as well as practical.
“Harry has spent the better part of the last five years arguing that the changes made to his protection arrangements after he stepped back from royal duties have left him, Meghan and their children exposed when they travel to Britain. Because of that history, developments involving security and other royal-connected figures inevitably attract his supporters’ attention.
