S4C will mark the 50th anniversary of the investiture of Prince Charles as Prince of Wales with a revealing documentary that tells the story through the eyes of protest singer and language campaigner Dafydd Iwan.

In the programme Dafydd Iwan: Y Prins a Fi to be aired on Sunday, 7 July, one of the central figures in the national movement over six decades embarks on a personal journey to shed new light on one of the most controversial events in Wales during the 20th century.

With some 500 million watching the colourful ceremony on television, the eyes of the world were on Wales and Caernarfon; the pomp and pageantry was enjoyed by most people in Wales, the UK and the world, but caused resentment, anger and resistance among some Welsh nationalists.

“The response to the protests against the investiture was the greatest hatred I’ve experienced in politics. Terrible things were said, and my life was literally threatened, both in print and verbally,” said Mr Iwan, who was a 25-year-old campaigner at the time of the investiture.

“Unfortunately, Charles was portrayed as a symbol of purity and perfection and I as the devil incarnate and public enemy number one.”

At the time of the investiture, Mr Iwan was chairman of the Cymdeithas yr Iaith Welsh language society.
