[citation needed] Powell has consistently attended the annual Cilmeri commemoration to mark the last battle of Prince Llywelyn.

[14] In January 2014, the BBC[15] and Western Mail[16] reported that Powell had been given a formal warning by the Liberal Democrats for inappropriate behaviour towards a young female party activist.

In July 2014,[17] Powell hit out at Alun Davies AM for seeking to gain personal information on him and four other Assembly Members, Andrew RT Davies, Llyr Huws Gruffydd, Kirsty Williams and Antoinette Sandbach, regarding EU farming subsidies received by their respective family businesses.

Alun Davies believed this caused a conflict of interest, however the Minister's actions led directly to his sacking by First Minister Carwyn Jones and Alun Davies subsequently issued a personal apology to all AMs involved regarding EU farming subsidies received by their respective family businesses.

He spoke about the topic during Plenary sessions, and worked with energy companies to try and advance their case, whilst at the same time ensuring that the communities and businesses he represents have their voices heard.

[2] Following the resignation of Kirsty Williams, Powell was chosen as the Liberal Democrat candidate for Brecon and Radnorshire at the 2021 Senedd election.
