Prince Harry and Meghan Markle were married today at a star-studded ceremony at St George's Chapel in Windsor.

Amal and George Clooney, Victoria and David Beckham, Oprah Winfrey, Carey Mulligan and Marcus Mumford, Elton John, and Serena Williams were among the many celebrities in the 600-strong congregation.

Before the ceremony took place, it was announced that the couple will be known as the Duke and Duchess of Sussex.

Meghan Markle’s wedding dress was designed by the acclaimed British designer, Clare Waight Keller, the first female Artistic Director at the historic French fashion house Givenchy.

The bridal dress was a simple, pure white gown, with three-quarter length sleeves and open bateau neckline.

Meghan's delicate veil was five metres long and made from silk tulle with a trim of hand-embroidered flowers in silk threads and organza, with her two pageboys carrying the ends as she made her way up the steps.
