Prince Harry has been left red-faced after the prime minister of Antigua invited him and his new girlfriend to return to the island – on their honeymoon.

The prince was visiting Antigua on Monday, as part of a 15-day tour of the Caribbean, when he met the country’s leader, Gaston Browne.

In a speech to the prince and hundreds of guests, Mr Browne told Harry: “I understand that there may be a new addition to the Royal Family very soon.

“I am told that there may be a princess and I just want to say that should you make the decision to honeymoon then Antigua and Barbuda want to welcome you.”

Seizing on the opportunity to promote the islands further, he continued: “We have been voted consistently as the best honeymoon destination in the Caribbean and one of the best in the world so there will be nowhere in the world as special to spend your honeymoon when that day arrives.”

Harry, who is believed to have begun dating actress Ms Markle in September, appeared to grimace at the comments and looked down at his feet.
