The party's decision-making bodies on a national level formally include the National Executive Committee (NEC), Labour Party Conference and National Policy Forum (NPF)—although in practice the Parliamentary leadership has the final say on policy. The 2008 Labour Party Conference was the first at which affiliated trade unions and Constituency Labour Parties did not have the right to submit motions on contemporary issues that would previously have been debated. Labour Party conferences now include more "keynote" addresses, guest speakers and question-and-answer sessions, while specific discussion of policy now takes place in the National Policy Forum.

When was the first time trade unions had the right to submit motions?
