Heledd Fychan becomes cabinet minister for culture and sport, a role promoted from a junior ministerial one in the last Labour government.
Fychan previously had a senior job at Museums Wales before joining the Senedd in 2021. She will also be trefnydd – which involves organising government business in the Senedd.
Former Plaid leader Adam Price was appointed the minister for enterprise, connectivity and energy, while minister for rural resilience, responsible for farming, is Llŷr Gruffydd – his party’s former rural affairs spokesman.
Meanwhile former Plaid Cymru MP Elfyn Llwyd will be returning to frontline politics as counsel general – the government’s chief legal adviser.
In a quirk of the system, the Senedd will need to be agree the role.
New MS Dafydd Trystan will be the minister for the constitution and government effectiveness, having previously held major roles within his party.
They include being chairman under former leaders Leanne Wood and Adam Price, and chief executive under Ieuan Wyn Jones.
