Tributes have been paid to former Plaid Cymru leader Dafydd Elis-Thomas - described as a ‘groundbreaking MP’ - who has passed away at the age of 78.

Lord Elis-Thomas also served as the Welsh Government's culture, sport and tourism minister from 2017 to 2021.

Dafydd Elis-Thomas led Plaid between 1984 and 1991 and served as MP for Meirionydd and then Meirionydd Nant Conwy between 1974 and 1992, when he was appointed to the House of Lords.

He served as his party's leader between 1984 and 1991 and as MP for Merioneth, later Meirionnydd Nant Conwy, from 1974 to 1992.

He quit Plaid Cymru in 2016 and continued to sit as an independent member of the Senedd for Dwyfor Meirionnydd, until he stepped down at the 2021 election.

Following the sad news of the passing, Plaid Cymru Leader Rhun ap Iorwerth MS said: “Dafydd’s passing will be a huge loss to Welsh politics and the civic life of Wales.

“He was unquestionably one of the most influential figures of his generation, and as the Presiding Officer of the First Assembly made a priceless contribution in laying the firm foundations of devolution.

“We remember Dafydd as a groundbreaking MP when he became the youngest Member of the 1974 UK Parliament before leading Plaid Cymru with passion and distinction.

“Dafydd was a personal friend to my family and I, and was an influential figure during my formative years.

“His love for our nation, its language and culture was unwavering.

“On behalf of Plaid Cymru, I extend our sincerest condolences to Dafydd’s family.”

Lord Elis-Thomas was described as the "Senedd's founding father" - and flags will fly at half-mast outside the Senedd building today in tribute.

Wales’ First Minister Eluned Morgan said: “It is with profound sadness that I learned of the passing of my dear friend and colleague, Lord Dafydd Elis-Thomas.

“Wales has lost one of its greatest servants, and many of us have lost an irreplaceable friend.

“Dafydd was a true giant of Welsh politics and a passionate champion of our nation, our language, and our culture. From his groundbreaking role as the first Presiding Officer of the National Assembly for Wales to his service in both Houses of Parliament, he helped shape the Wales we know today.

“On a personal level, Dafydd was an inspiration to me from my earliest days in politics. His ability to remain true to his principles while working constructively across party lines showed me what truly effective public service could look like.

“I had the privilege of working alongside him in the House of Lords, the Senedd and Welsh Government, where his warmth, wisdom, and unwavering commitment to Wales were extraordinary,” she continued.

“What I'll remember most about Dafydd was his infectious enthusiasm for Welsh culture and dedication to preserving our language. He was equally at home discussing medieval Welsh poetry as he was debating constitutional reform - a true Renaissance man who embodied the very best of Welsh intellectual tradition.

“Beyond politics, Dafydd was a kind and generous friend, always ready with wise counsel or a warm word of encouragement. His mischievous sense of humour and storytelling abilities made every conversation memorable.

“Wales has lost one of its most distinguished servants, and I have lost a dear friend. Our nation is immeasurably richer for his lifetime of service, and his vision of a proud, confident, and culturally vibrant Wales will continue to inspire generations to come,” she added.
