LONDON — One of the last remaining mysteries of the wedding of Meghan Markle and Prince Harry on Saturday has been cleared up: who will walk her down the aisle.

Prince Charles, the father of the groom, will do the honors for part of the way, according to a statement from Kensington Palace on Friday. Apparently, Ms. Markle will start the walk on her own and meet him at the choir.

“Ms. Meghan Markle has asked His Royal Highness the Prince of Wales to accompany her down the aisle of the Quire of St. George’s Chapel on her wedding day,” the statement said.
