Prince Charles will walk Meghan Markle down the aisle as she marries his son Prince Harry on Saturday in London.

In a statement, Kensington Palace said: "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 Prince of Wales is pleased to be able to welcome Ms Markle to The Royal Family in this way."

On Thursday, Meghan addressed the speculation around her father's health and role in her wedding, with Kensington Palace posting a statement on her behalf.

"Sadly, my father will not be attending the wedding. I have always cared for my father and hope he can be given the space he needs to focus on his health," she said.

"I would like to thank everyone who has offered generous messages of support. Please know how much Harry and I look forward to sharing our special day with you on Saturday."
