During the 2011 referendum on extending the National Assembly for Wales's law-making powers, Wood was Plaid Cymru's representative on the all-party Yes for Wales steering group, which campaigned successfully for a 'Yes' vote. She is Chair of the PCS Cross-Party Group in the Welsh Assembly. According to the BBC, Wood's particular areas of interest are: poverty; women's issues; social services; criminal justice; social exclusion; mental health; anti-privatisation; and anti-war. Her Plaid Cymru profile includes her commitment to working "for Wales to become a self-governing decentralist socialist republic".
