Meghan Markle has been spotted in costume taking her children Prince Archie and Princess Lilibet trick or treating for Halloween – but their father Prince Harry seemingly forgot his fancy dress.

Prince Archie six, was seen eagerly running to an extravagantly decorated house in an ant costume while his sister Princess Lilibet, four, was already two steps ahead of him collecting sweets at the front door.

The little girl, who is understood to have only met her grandfather King Charles on one occasion, was dressed as a fluorescent green firefly. Wearing a black tracksuit and sunglasses, Meghan appeared to coordinate with her children’s bug-themed outfits as she wore colourful butterfly wings.

Harry, on the other hand, did not buy into the spooky spirit, wearing a light blue baseball cap with a navy polo shirt and jeans. The Duke appeared to be carrying a water bottle in his left hand, with another sticking out of his back pocket, while Meghan appeared to hold a Thermos cup.

Royal watchers will find it a shame that Harry has seemingly left his costume at home as the Sussexes have previously spoken of the special place Halloween holds in their hearts.
