The Green Party has secured a referendum on the legalisation of cannabis for personal use as part of its deal to support the next government, according to party documents.
The Greens have been given three ministerial portfolios in their key policy areas, but will sit outside of cabinet in a confidence and supply agreement with the next Labour-led government.
An email circulated around the party's delegates last night lists "a referendum on legalising the personal use of cannabis at, or by, the 2020 general election" among policy gains under its agreement with Labour.
The long list of concessions also includes the "overhauling" of the welfare system, including removing "excessive sanctions"; a significant increase in the Conservation budget; and free counselling for under-25s.
Other areas listed in the letter include new water quality measures, working towards ending the gender pay gap and reducing student hardship.
