Prince Harry will attend the Invictus Games' 10th anniversary service in the UK next week, amidst speculation about a meeting with his father, King Charles.

King Charles, who has been diagnosed with cancer in February, is responding well to treatment and resuming public duties, including a visit to a cancer treatment centre.

Prince Harry and Meghan Markle have plans to visit Nigeria, a country with which Meghan has a personal connection due to her Nigerian heritage.

King Charles is scheduled to host the Japanese Emperor for a state visit in late June.

The upcoming trips for Prince Harry and Meghan Markle tie in with their ongoing security challenges in the UK and the discussion of Nigeria potentially hosting a future Invictus Games.
