Ap Gwynfor stood for election to the British Parliament and Senedd unsuccessfully on several occasions between 2005 and 2016. He contested the Brecon and Radnorshire seat at the 2005 general election. He attempted to be selected as Plaid Cymru candidate for Ceredigion in 2010, but was not successful.

Shortly after he was elected, in August 2021, he resigned as councillor for Llandrillo.
