A short note on how Labour’s Leadership election rules work.
Rule Ch1.Vii establishes the roles, and delegates the election process to Ch4.II.
This from C1.VII, is quite amusing given the history of the last few years, underling is mine.
The Leader shall, as a member of the NEC, uphold and enforce the constitution, rules and standing orders of the Party and ensure the maintenance and development of an effective political Labour Party in parliament and in the country.
Chapter 4.II defines the nomination and election process. The first clause is the now sadly common rule that claims to establish a principle but actually allows the NEC to vary the process and either bend or break the rules. Any such variation would need to be conformant with Wedensbury reasonableness rules, but this is unlikely to be ever tested in a court.
The rules specify process to be followed in the case of a vacancy, or where no vacancy exists.
To be a valid nominee, a candidate requires nomination from the PLP, CLPs and affiliates. In the case of a vacancy, the rules are silent as to the order these are to be sought.
In the case of a challenge, someone would have needed to have collected the 20% of the PLP supporters, and then others would need to be given the opportunity to do so too. The timing of the making of supporting nominations by CLPs and affiliates is also silent.
The rules state that nominations shall be made by all three classes of nominators.
The election consists of a one member one vote and is designed to include union political levy payers, who are not members of a political party. This I thought interesting,
4.II.C.vii The precise eligibility criteria shall be defined by the NEC and set out in procedural guidelines and in each annual report to conference.
as yet again neither members nor candidates know the rules until after the election has been called and nominations made. See also the Rule Book 2026 and/or My Repo, which holds mirrors
