LONDON — Buckingham Palace confirmed Friday that Prince Harry and his wife, Meghan, will not be returning to royal duties, and Harry will give up his honorary military titles, a decision that makes formal, and final, the couple’s split from the royal family.

When Harry and Meghan stepped away from full-time royal life in March 2020, unhappy at media scrutiny and the strictures of their roles, it was agreed the situation would be reviewed after a year.
