The Government of Wales Act 2006 provided the National Assembly for Wales with significant new powers to legislate, and strengthens its scrutiny role. It also creates a legally separate Welsh Government and a Corporate Body, known as the National Assembly for Wales Commission (Assembly Commission) which has responsibility for the provision of property, staff and services to support the Assembly Members. The Commission consists of the Presiding Officer and four other Members nominated by the main political parties. The staff of the Commission are employees of the Commission and are headed by the Chief Executive and Clerk to the Assembly.
