Having attended Welsh-medium education in Cardiff, Eluned Morgan studied European Studies at the University of Hull and worked as a TV researcher before being elected to the European Parliament in 1994. The youngest elected MEP, she became the Labour Spokesperson on Industry, Science and Energy, and on budget matters, before she stood down in 2009 and began working for an energy company.
In 2011, Eluned was granted life peerage in the House of Lords and is formally known as Baroness Morgan of Ely. From 2013-16, Eluned served as Shadow Minister for Wales in the Lords and from 2014-16 as Shadow Minister for Foreign Affairs.
Eluned Morgan served on the Welsh Labour Party Executive for ten years and was appointed to the Welsh Assembly Advisory Group which was responsible for developing the standing orders of the National Assembly of Wales. She was a founding member of the Yes for Wales Cross Party Group which campaigned for the Assembly to be established.
Eluned joined the Assembly in 2016 as the regional member for Mid and West Wales. In November 2017, she was appointed as the Minister for Welsh Language and Lifelong Learning and leads on skills for the Welsh Government.
Mark began his working life in the probation service and with young people in the justice and care system, before an academic career that saw him appointed as a Professor of Social Policy and Applied Social Sciences at Cardiff University. A Welsh-speaker originally from Carmarthenshire, he was elected as Labour councillor in South Glamorgan in 1985.
He worked side by side with Rhodri Morgan as his Senior Special Adviser throughout his premiership, and then won the Cardiff West seat in 2011 when the former First Minister stood down. During this period, he helped shape the progressive universalism that was an important element of the ‘clear red water’ between Labour governments in Cardiff and London.
He focused on health and social policy, and helped reshape health boards in Wales, whilst also overseeing the ‘second offer scheme’ to reduce waiting times.
Following a period as the Chair of the Health Committee, he was soon promoted to the cabinet as Health Minister, and oversaw the organ donation legislation. His focus included mental health and social inequality in the health service.
Appointed as the Minister for Finance and Local Government in 2016, he attempted to rebalance the relationship with local government. At the last reshuffle, he was appointed as the Cabinet Secretary for Finance, and has led on the Welsh Government’s negotiations with the Treasury on Brexit, as well as help shape budget deals.
Vaughan was born in Lusaka, Zambia, where his Welsh father was working as a vet. The family moved back to the UK when he was two, and he then attended Aberystwyth and Cardiff Universities, and became the first black president of NUS Wales.
Having qualified as a solicitor, he worked for Thompsons, a firm well known for representing trades unions and its members in disputes. He became a partner in 2007. Through his heavy involvement in the trades union movement in Wales, he became the first black president of TUC Wales.
Elected in 2011, he was promoted to Deputy Minister for Health in 2014, becoming Cabinet Secretary for Health, Well-being and Sport in 2016.
His focus as Health Secretary has to some degree been on LHB delivery and tackling the increased demand on elements of the NHS, whilst also promoting public health initiatives, attracting more doctors to Wales and improving emergency medicine.
