Prince William jokes about his 'Harry Potter scar' from a golfing accident

Prince William mentioned the golfing accident which left him with a head wound during a fact-finding visit to Wales to learn more about businesses and organisations utilising the benefits of seaweed.

Entrepreneurs gathered at Cardiff Metropolitan University to discuss investment in the sector and display products based on what Derek Walker, future generations commissioner for Wales, dubbed the super-power of seaweed.

William chatted to Pierre Paslier, the co-founder and co-chief executive officer of Notpla, which supplies seaweed packaging to major sporting and music venues across the country.

The heir to the throne then picked up a seaweed-produced golf tee, made to biodegrade and fertilise greens, and when asked if he played golf, Mr Paslier said the royal replied "no, the last time I played golf" and pointed to his head.

It was during his five years at Ludgrove school that William suffered a golfing accident that left him with his "Harry Potter" scar when a young boy.

Notpla is a former category winner in William's Earthshot environmental prize and the prince has taken a keen interest in the business.

The firm's seaweed-based products are supplied to Levy, a leading sports and entertainment caterer, and used in more than 50 venues from the Oval to Wimbledon's All England Lawn Tennis Club and London's O2 Arena.

Taking to Instagram, Willam posted a picture of himself on a train on the way to "celebrate seaweed innovation" earlier today.

Posted on stories, accompanied the picture read: "En route to Cardiff today to celebrate seaweed innovation!"

The Instagram account @princeandprincessofwales also wrote the same in Welsh: "Ar y ffordd i Gaerdydd i ddathlu arloesedd mewn gwymon!"

A second post said: "Seaweed is one of the most abundant resources on the planet, and it is a potential solution to some of the biggest environmental problems felt across the World."

Today, William attended an event highlighting global businesses using seaweed across a number of industries.

During his surprise visit to Cardiff, the royal will also see firsthand how Wales is helping food and drink businesses locally and around the world through food science, new product development and biomedical sciences.

The visit came as a surprise after it emerged that many royal engagements will be cancel in the run-up to the general election next month.

Buckingham Palace shared a statement last month, which read: "Following the Prime Minister's statement this afternoon calling a general election, the royal family will - in accordance with normal procedure - postpone engagements that may appear to divert attention or distract from the election campaign.

"Their Majesties send their sincere apologies to any of those who may be affected as a result."
