Uganda's military chief has announced the country's withdrawal from the Invictus Games, citing the ongoing controversy surrounding Prince Harry and Meghan in relation to the British royal family.

In an overnight post on social media, General Kainerugaba stated: "In order not to be construed as being opposed to His Majesty King Charles III of the United Kingdom, whom we deeply revere, Uganda hereby withdraws from the Invictus Games."

He added: "We shall not participate in anything that does not have His Majesty's approval."

The announcement followed a letter sent this week on behalf of King Charles which made clear that Prince Harry and Meghan, who have since returned to the United Kingdom, are not working royals.

Reports quoted the general's concerns about what he described as the "Harry-Meghan nonsense", suggesting this was the background to the withdrawal decision.

Royal sources, however, have said that the King encourages all projects which support wounded service personnel.

A spokesman for the Invictus Games said the organisation had not received any official information about a potential withdrawal and had been seeking clarification from its contacts in Uganda.

Uganda's participation in the next games, to be held in Birmingham next year, was announced in July, when Prince Harry was in London promoting the event. Uganda had become the 26th country to take part in the games, which celebrate the resilience and rehabilitation of wounded military personnel.

General Kainerugaba also posted other messages on the same day. One read: "I consider myself the most handsome, most daring and glorious Commander who ever lived." There was also a series of messages expressing anger at other generals who had danced without his permission.
