Queen Elizabeth calls a meeting to address the royal family crisis.

LONDON — Queen Elizabeth II has summoned her son and heir Prince Charles and grandsons Princes William and Harry to a crisis meeting to sort out plans by Harry and his wife, Meghan, to “step back” from their duties as senior royals

Elizabeth, who assumed the throne in 1952, has weathered family crises before and is determined not to let her restless grandson and granddaughter-in-law weaken the House of Windsor or undermine the monarchy.

After initial talks between courtiers to the senior royals over the couple’s unorthodox declaration of independence, Buckingham Palace said Saturday that the queen would meet Monday at her Sandringham estate in eastern England with Charles, William and Harry to agree on “next steps.”

The palace said “a range of possibilities” was on the table, but the queen was determined to resolve the situation within “days not weeks.”

Harry’s next scheduled public appearance is a rugby event at Buckingham Palace on Thursday. Meghan, meanwhile, has flown to Canada, where the couple and their 8-month-old son, Archie, spent a six-week Christmas break. They announced this past week they plan to “balance” their time between the U.K. and North America, with Canada their likely base. Meghan is American but lived in Toronto for several years while filming the TV show “Suits.”

While Harry and Meghan’s plans have drawn a mixed response in Britain, there has been near-universal sympathy for the queen. That extended to President Donald Trump, who said Friday that the family situation she’s dealing with was “sad.”

“I just have such respect for the queen,” Trump told Fox News. “I don’t think this should be happening to her.”
