Prior to 2008, the Green Party elected spokespeople called principal speakers instead of leaders. After a rule change, the party adopted a system of electing a leader or co-leaders every two years. If there are two co-leaders, a single deputy will be elected whereas if there is a single leader there are two deputies.
This brief starts where responsible research should: with the source description of “2018 Green Party of England and Wales leadership election” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q55076690. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018, 2016 and 2008.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
