Plaid Cymru ministers have stated that significant progress has been made in their first 100 days in government, completing the initial work on 96 actions outlined in their plan. Dafydd Trystan Davies reported that foundations for success have been laid and tangible progress is already being felt in some areas. The first minister is currently on leave and unavailable for interviews, with Rhun ap Iorwerth slated to issue a formal progress report next week.

However, opposition parties have voiced a different assessment. Reform accused Plaid Cymru of prioritizing "reviews, committees and plans" over action, with Welsh leader Dan Thomas asserting that conditions have worsened, citing an increase in waiting lists. He pointed to the first minister's election campaign promise to eradicate two-year waits within months, a goal that remains unmet three months into the administration.

Ken Skates, leader of Welsh Labour, drew a contrast between Plaid Cymru's early tenure and the start of Andy Burnham's premiership, characterizing Plaid's approach as "a lot of talk, very little action." In contrast, Skates highlighted "really, really big interventions" made under Burnham's leadership that are expected to impact people's lives.

Darren Millar MS, Leader of the Welsh Conservatives in the Senedd, described Plaid Cymru's first 100 days as a "disappointing series of missed opportunities" to alter the political landscape after 27 years of Labour rule in Wales.
