September Policy Assembly: Building a Better Tax System

TIME:
Wednesday, September 16, 2026
18:00
LOCATION:
Zoom

Mainstream isn't just about organising. We understand that Labour needs a radical realist policy platform that will help us to win the next election on terms that don’t just defeat the threat of national populism, but win hearts and minds for the long-term transformation of our country.

At our September Policy Assembly, we'll turn our attention to how Labour should reform the tax system. We'll be joined by leading economists and campaigners to explore what a progressive, sustainable tax settlement could look like, why it matters, and how we can build the public and political support to achieve it.

All Mainstream members are warmly invited to join us at 6pm on Wednesday 16th September to help shape the debate on building a better tax system.

Mainstream's Policy Assemblies are a space for our members to build power, share ideas and create campaigns for a bolder, broader and brighter Labour Party.

You must be a member to join our Policy Assembly. Not yet a member? Join here to participate.
