The suede Matilde heels feature an intricate strapped design which wraps around the foot and ankle before tying up with a bow just above the heel.

They currently retail at £620 and were previously worn by Eugenie to another royal wedding, that of Prince Christian of Hanover and his wife Alessandra de Osma.

Her Joseph dress is also available at half price, down from £545 to £272, and her Emily London Sabina Pillbox Hat is on sale for a cool £885.

The Sunday Times reported: “Hugh is one of the very few close friends of William and Harry’s who has maintained strong bonds and a line of communication with both.

“He wishes they could put their heads together and patch things up, but realises it’s unlikely to happen before the wedding. He wanted to avoid anything overshadowing the day, especially for Olivia, and doesn’t want any awkwardness.”

Princess Kate was also unable to accompany William to the wedding, as she remains out of the spotlight while she continues her cancer treatment.
