According to that funding page, they will retain their titles, they will continue to work on behalf of The Queen and during that work they will receive taxpayer funded security. No answer as to who will pay for their security when they undoubtedly fly to the USA and promote The Sussex Foundation on Oprah...
They really are, attempting badly, to have the best of both worlds. It's absolutely ridiculous, and embarrassing.
If they want "that" life, then give up this one. To keep their titles, the security, the benefits and still want the peace, quiet and the life that Vancouver Island offered them, it's just not going to happen. What was the point of handing over patronages, applying for British Citizenship, marrying a british royal, for you to turn around and want none of it? I've said this since they married, I know Henry has spoken of his lack of desire to be a part of the British Royal Family before Meghan so it's simple. Leave.
I would be absolutely fine with this announcement, if they'd given up their titles at the same time.
