The Prince of Wales has paid tribute to former Wales and British and Irish Lions full-back JPR Williams.

William, patron of the Welsh Rugby Union, posted a personal post – denoted with a W at the end of his message – in honour of Williams, who has died at the age of 74.

The prince said on X, formerly known as Twitter: “There was no one quite like him on the rugby field. A true @WelshRugbyUnion great, my thoughts are with JPR Williams’ family and friends. W.”

Williams, a fearless player known for his aggressive and attacking style, won 55 Wales caps and started all eight Tests on victorious Lions tours to New Zealand in 1971 and South Africa three years later.

He was revered among fellow Wales greats like Sir Gareth Edwards, Barry John, Phil Bennett and Gerald Davies and regarded as one of rugby union’s finest players.

A star performer during Welsh rugby’s 1970s golden era, he also captained his country on five occasions.

And Williams shone for the Barbarians in their unforgettable 23-11 victory over New Zealand in 1973, touching down in a game chiefly remembered for Edwards’ spectacular touchdown that completed a breathtaking length-of-the-field move.

Welsh Rugby Union president Terry Cobner, who played alongside Williams for Wales during two Five Nations Grand Slam-winning campaigns, saluted his contribution to the sport.

“Welsh rugby will remember him as one of our greatest players of all-time – those 55 caps, three Grand Slams and six Triple Crowns prove that,” Cobner said, on the WRU’s official website.

“He also played in all eight Tests in New Zealand and South Africa on arguably the two greatest tours undertaken by the Lions in 1971 and 1974.

“It was his drop-goal from near halfway that enabled the 1971 Lions to draw the fourth Test and win the series 2-1 against the mighty All Blacks – the only series victory by the Lions on New Zealand soil.

“A star in the making from his early school days at Bridgend Grammar, then at Millfield, he went on to thrill crowds at both London Welsh and Bridgend on the club scene. He was ‘box office’ wherever he went.

“This is a terrible loss for our game, but obviously an even worse loss for his wife, Scilla, and their three four children.

“The thoughts of the whole Welsh rugby family are with them at this difficult time.”

There were also tributes on social media from Wales’ Six Nations rivals Scotland and Ireland.

“JPR, the three most famous letters in sport if you lived in the 1970s,” Scottish Rugby said on X.

“Scottish Rugby extends its sincere condolences to family and friends of JPR Williams – and the rugby community in Wales – after the death of the former Wales and Lions full-back was announced yesterday.”

And Irish Rugby said on X: “A joy to watch on the field and a gentleman off it. Rest in peace JPR Williams.

“Our thoughts and prayers are with his friends and family.”

Such was Williams’ natural fitness that he continued playing into his early 50s for village club Tondu, often in the back-row, before finally hanging up his boots in 2003.

“We are devastated to share the news our club patron JPR Williams has passed away,” Tondu Rugby Club said on X.

“John was one of our game’s greatest players and will be missed by all at Tondu RFC. Our thoughts and prayers are with John’s family and close friends at this incredibly sad time.”
