Prince Harry will not be traveling to London to attend a service honoring the life of  Prince Philip later this month.

The Duke of Sussex’s spokesperson confirmed he would not be attending the March 29 Service of Thanksgiving event at Westminster Abbey. The private event will be used to memorialize the Duke of Edinburgh who died April 2021 at 99 years old.

Prince Philip’s funeral service had a pared-down audience of 30 members of the royal family, including Queen Elizabeth II, and was closed to the public, due to COVID-19 restrictions.

Prince Harry — who lives in California with his wife Meghan Markle and two children Archie, 2, and newborn Lilibet — returned to England for his grandfather’s April funeral and also returned during the summer to see a statue of his mother, Princess Diana, unveiled.

Harry has expressed hesitation returning to his home country due to security concerns. He is currently embroiled in a legal battle with the British government over whether he and his family will have protection when in the United Kingdom.

The British government says he’s not entitled to taxpayer-funded protection because he’s no longer a working royal, though Harry argues that the threat level against himself and his family remains high.
