Prince Harry is “extremely disappointed” that he may be forced to change his plans to return to the UK next month, according to a royal insider.

The Duke of Sussex was scheduled to travel back to London in May to attend the celebrations for the 10th anniversary of the Invictus Games.

However, a source close to the royal has now suggested he could be “forced to consider” cancelling amid ongoing security concerns for himself and his family.

The Duke earlier this year lost a challenge against the Home Office protesting the decision to remove his security detail after he and Meghan Markle stepped down from their official roles.

The insider said: “Whenever Harry travels to the UK, his trips are always dependent on how secure he is. Before deciding whether to attend the Invictus Games anniversary event, his security team must be sure that St. Paul’s is adequately protected by the metropolitan police and his own security needs are met while he’s in London.

“Harry wants to spend more time in the UK with his family, but there’s no way he can do that while a question mark hangs over his security detail.”
