LONDON — There is no such thing, it turns out, as being a part-time royal.

The severance deal that Buckingham Palace announced on Saturday for Prince Harry and his wife, Meghan, is most remarkable for how clean a break the royal family is making with two of its most popular, if disaffected, members — much more severe than the couple apparently expected.

The British news media, which has likened the couple’s split with the royal family to Brexit, lost no time on Sunday in pronouncing the agreement the equivalent of a “hard Brexit,” similar to the uncompromising trade deal that Prime Minister Boris Johnson is expected to pursue with the European Union this year.

[Update: Prince Harry and Meghan exit Britain with final official engagement.]

Far from carving out a “progressive new role within this institution,” as the couple hopefully declared when they unexpectedly announced their plans to “step back” from royal duties this month, Harry and Meghan will lose most of the privileges and perks of royalty once they give up their full-time status and forsake Britain for an uncertain future in Canada and the United States.

Under the terms of the agreement, the couple will no longer use their most exclusive titles, His Royal Highness and Her Royal Highness, will forgo public funding of their activities and will repay more than $3 million for the refurbishment of Frogmore Cottage, their residence on the grounds of Windsor Castle.
