This Act established the National Assembly for Wales as a corporate body with an executive government and a legislating body, and passed the governance of the NHS in Wales from the UK Parliament to the Welsh Government and the Welsh Minister for Health and Social Services. A subsequent Government of Wales Act 2006 provided the Welsh National Assembly with primary legislative powers in a number of areas including health. The UK Government retains responsibility for UK-wide areas such as tax, defence, foreign policy, social security and welfare benefits.
