Prince Harry and Meghan Markle are among the royal family members who headed to Buckingham Palace on Tuesday for the arrival of the Queen’s coffin, The Post has learned.

Queen Elizabeth died Thursday in Scotland, and her body was returned to England on Tuesday as part of the nation’s 10-day period of mourning.

While Harry rushed to the Queen’s side before her death, ultimately not arriving in time, Meghan was told she was unwelcome, Page Six reported.

“Tensions were so high and there was no way Meghan could have gone to Balmoral,” a palace insider said Friday.

But our sources tell us they are expected at the palace, along with Prince William and Princess Kate.

Mourning the Queen has added tension to the couple’s already difficult relationship with the rest of the family.

Estranged royal brothers Prince William and Prince Harry “required extended negotiations” before their joint public appearance Saturday to pay tribute to Queen Elizabeth II and greet mourners, according to reports.
