Dewi Watkin Powell was one of Wales’ best-known judges - a fervent supporter of the Welsh language and of Plaid Cymru.
As well as being a Crown Court judge and then a High Court judge, he gave evidence to commissions looking at options for the future governance of Wales with the likes of Gwynfor Evans and Dafydd Wigley in the 1960s and 1970s.
He later chaired the council of University College, Cardiff, sat on the governing councils of other Welsh universities and was a member of the Gorsedd of Bards. Among other distinctions, he also became President of the Baptist Union of Wales and of the Council of Free Churches.
