Make Votes Matter is "the cross-party campaign to introduce Proportional Representation to the House of Commons, led by democratically-organised activists in a united movement for electoral reform.

[6] Most recently, the campaign has orchestrated national days of action for Proportional Representation such as Hungry for Democracy on 6 February 2018 in which 407 people joined a 24-hour "hunger strike".

[9] The action day saw volunteers organise events in over 60 towns and cities across the UK from Truro to Aberdeen.

[12] According to polling by YouGov in December 2019 three-quarters of Labour members believe the party should commit to supporting proportional representation and adopt it as a policy.

[14] A later poll by YouGov in September 2021 suggested this number had risen to 66% of Labour Party voters supporting proportional representation.

[26] Since the party's previous conference in 2021, more trade unions including the two largest in Unite and Unison have voted among themselves to embrace support for proportional representation.

[25] The decision by Keir Starmer has received criticism from multiple figures within the party, including Mayor of Greater Manchester, Andy Burnham, former Shadow Chancellor of the Exchequer, John McDonnell, and Neal Lawson who chairs and helped set up the Labour affiliated think tank, Compass.
