In 2007 the Government of Wales Act 2006 came into force and powers were give to the Assembly to make laws, called Assembly Measures, for Wales in defined areas with the permission of the UK Parliament. Following a 'yes' vote in the 2011 referendum further law making powers were given to the Assembly and it is now able to pass laws, known as Acts of the Assembly on all subjects in the twenty devolved areas without needing the agreement of the UK Parliament. In 2020 the National Assembly for Wales was renamed Senedd Cymru/Welsh Parliament.
