Queen says she will use 'final trump card' to send major warning to Harry, Meghan

Queen Elizabeth has sent alarm bells ringing as she warned Prince Harry and Meghan Markle to stop exploiting her name Lilibet. 

Earlier this week, a spokesperson for the Duke and Duchess of Sussex revealed they registered domain names for their daughter, named after the Queen.

Royal expert Daniela Elser claimed the 95-year-old monarch will use her 'final trump card' to threaten the Sussexes to not let them cash in on the name.

She wrote in Australia's Daily Telegraph: "All of this might be a storm in a cup of vegan latte and those domain names may very well sit dormant for the rest of time.

"But, if they don’t, if they are used for any sort of lucrative endeavour, the Queen could be forced to act to even more assertively cleave the Sussexes from the monarchy to try and protect the crown.

"Having lost their ability to use their styling as His/Her Royal Highness, having lost their official royal patronages and Harry having lost his honorary military roles, the final remaining official tether is their Sussex title, which was gifted to them for their wedding," Elser added. 

"Could there come a day when Buckingham Palace plays this – their final trump card – and consider using the threat of forcing their Sussex titles into abeyance to bend the renegade duo to their will? (Whether such a strongarm tactic would work is another question entirely).

"Would the palace be quite so lenient and so willing to turn a blind eye if there ever came a day that Lili’s name was used in conjunction with any sort of money-spinning outing? We may well find out sooner rather than later," the expert concluded.
