"The National Executive Committee is the governing body of the Labour Party, overseeing the overall direction of the party and the policy-making process. It sets strategic objectives on an annual basis and meets regularly to review the work of the party." https://labour.org.uk/about/how-we-work/ 

"All members of the NEC are members of the National Policy Forum. This body oversees the development of party policy through a rolling programme of policy development. Throughout the year, NEC members participate with shadow government ministers in Labour Party policy commissions that prepare reports on different areas of policy which are then presented to and consulted on with the party membership before going to annual conference.

​This forms the basis of Labour’s general election manifesto. The NEC is also responsible for upholding the rules of the party and propriety of Labour selection processes."  https://labour.org.uk/about/how-we-work/national-executive-committee/whos-on-the-nec/ 

At Conference in September 2017, it was agreed to add a further 3 members to the NEC who would be elected by the membership.  Email Ballots will go out on 30th November to all members.  Candidates need nominations from 5 CLPs in order to stand.  See list opposite for CLP nomindations as at 17th November.

"Izzard, Baxter and Josan describe themselves as independents and pro-diversity although they appear on the same website. They are expected to pick up votes from members opposed to Corbyn." (https://labourlist.org/2017/11/labour-left-slate-dominates-nec-nominations-as-deadline-looms/)
