The Duchess of Cambridge has revealed that she regularly teaches her children about the importance of hugs.

The mother-of-three was at the Basildon Sporting Village with her husband, the Duke of Cambridge, to highlight the ability of sport to change lives.

She embraced young fans, along with Janet Emery, 58, who hugged both Catherine and Prince William.

"Thank you very much," Catherine told her. "Hugs are very important. I keep saying that to my children."

During the visit, the duchess played tennis, while the duke tried javelin practice, as they met young trainee coaches enrolled in the Royal Foundation's Coach Core project.

It aims to empower those not in education or employment by training them up as the next generation of sports coaches - who will hopefully go on to inspire their communities.

Hugging members of the Royal Family is said to break with traditional protocol - you are not meant to touch a royal when meeting them unless they offer their hand to you first to shake.

But ´óÏó´«Ã½ royal correspondent Jonny Dymond said these are "customs and practices" rather than "a book of rules".

You will not see the senior royals, such as the Queen or Prince Charles, handing out hugs.

But, for the younger generation, he says "nothing is set in stone", adding: "Reinvention is something they have become rather good at."

Prince Harry and Meghan Markle have flouted the tradition throughout their tour of Australia and New Zealand, embracing a number of well-wishers - one of which stroked Prince Harry's beard.
