Who was ex-Plaid Cymru leader Lord Elis-Thomas?

Former Plaid Cymru leader and Senedd Presiding Officer Lord Elis-Thomas has died at the age of 78.

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 was the first presiding officer, or speaker, of the new Welsh Assembly when it opened in 1999.

Lord Elis-Thomas was described as the "Senedd's founding father" as the BBC's Welsh affairs editor Vaughan Roderick explains.
