Prince Harry and Meghan Markle’s Nigerian visit is a reminder of how much the House of Windsor could have used them

Prince Harry and Meghan’s 72-hour visit to Nigeria has attracted a level of publicity Buckingham Palace has been sorely lacking of late.

The photographs of the former royals taking part in a casual volleyball game, accepting flowers from a little girl and visiting local schools to promote mental health awareness made headlines around the world over the weekend.

Prince Harry drew praise over a heartfelt speech about the importance of “acknowledging bad days”, and photographers snapped pictures as he accepted an invitation to sit and throw the ball around with army veterans wounded in battle against the country’s Islamist insurgency.

His wife’s instinctive sartorial choices were also avidly followed by royal and non-royal watchers alike, as was her special connection to the country she called “home”.

The lightning-quick tour of Nigeria was intended to champion mental health for young people and promote the Invictus Games, an international sporting event founded by Prince Harry back when he was still firmly within the royal fold.
