A biography of Lord Dafydd Elis-Thomas, former MP for Merioneth, former Senedd member for Meirionnydd Nant Conwy and the first Presiding Officer of the National Assembly for Wales, will be launched in Portmeirion this week.

The launch of Dafydd Elis-Thomas: Nation Builder by Aled Eurig, will take place at 6pm this Thursday, 2 September, in Portmeirion.

The book explores Dafydd Elis-Thomas’ political career from its beginning with his election to Westminster as a Plaid Cymru MP in 1974 to his retirement from the Senedd in Cardiff in 2021.

Elis-Thomas is regarded as a ‘founding father’ as the first Presiding Officer of the then National Assembly for Wales, stabilising the new institution and embedding devolution during its first tentative decade, and was described as a ‘true giant’ of Welsh devolution following his death in 2025.

He was a controversial and magnetic character, whose life and work is captured in this biography – branded a ‘maverick’, an ‘intellectual acrobat’ and a ‘political chameleon’, he was labelled a ‘terrorist’ for his interventions in Northern Ireland, and a ‘traitor’ for oppositional stances adopted towards nationalism. Despite a career often marked by controversy and fearless passion, his unique vision and perseverance was central to the creation of Wales’s first legislative parliament.
