Meghan Markle and Prince Harry will marry on Saturday, May 19 at Windsor Castle, Kensington Palace has revealed today.

The royal couple have chosen FA Cup Final day to walk down the aisle.

Meghan Markle made history this week after the Queen took the unprecedented step of inviting her to spend Christmas at Sandringham before she marries Prince Harry.

The star, 36, will spend the festive period at Her Majesty's private estate in Norfolk even though Kate Middleton was only asked after she walked down the aisle with Prince William in 2011.

The Queen's invitation to the US-born actress is further evidence of the royal family's warm welcome for her ahead of the couple's May wedding at Windsor Castle.

Meghan, who will take British citizenship and get baptised by the Church of England before the wedding, will also attend the Christmas Day service at St Mary Magdalene Church, Sandringham.

She and Harry, 33, who are now living together in a two-bed cottage in the grounds of Kensington Palace, will also take part in the traditional walk to mass by the entire royal family.

Confirming the news today a Kensington Palace spokesman said: 'You can expect to see The Duke and Duchess of Cambridge, Prince Harry and Ms Markle at Sandringham on Christmas Day.'
