Princes William and Harry

The 34-year-old royal was on an official visit in Luton, England, yesterday (24.08.16) when he was approached by Trish Cruse, 57, who asked for his brother's mobile number for her 27-year-old single daughter, Olivia.

But William, who was with wife Duchess Catherine, to present Hayward Tyler with the Queen's Award for Enterprise for their success in international trade, burst out laughing and replied, "Oh no! You don't want that!"

But Harry, 31, might not be impressed with his brother blocking a potential suitor as he recently revealed he wants to get married and start a family.

He said: "There come times when you think now is the time to settle down, or now is not, whatever way it is, but I don't think you can force these things it will happen when it's going to happen. Of course, I would love to have kids right now, but there's a process that one has to go through."

Harry has been single since splitting from ex-girlfriend Cressida Bonas in April 2014 after nearly two years of dating.

He previously dated Chelsy Davy for five years.

In May this year, Harry was asked by Jenna Bush if he would like to marry her twin sister Barbara.

The daughter of former US president George W Bush said: "You know what, I have a single sister and she feels the same way. Listen, she's available!"

Harry laughed and said: "We can talk maybe off air."
