[1] It is regarded by The Guardian, Politico, The Times, and Business Insider as a highly influential group upon the Starmer-led Labour Party,[1][2][3][4] and seen as an "incubator" of its 2024 manifesto.

[2][1] MP Jon Cruddas, in an attempt to prevent the wider party from fracturing, gathered other MPs including Steve Reed and Lisa Nandy to form the group.

[3] Labour Together during this time has been described by The Guardian as "initially such a broad church," with members such as former national coordinator of Momentum Laura Parker, as well as Miliband himself.

Before the launch, on 25 May, the group announced a "communities fund" for donations as well as an academy with the aim of teaching party members about campaigning, organising and leadership.

[12] The group received initial funding from Nevsky Capital founder Martin Taylor and Trevor Chinn, the latter of whom was appointed as Labour Together's director after donating £10,000.

In 2017, Morgan McSweeney took over as director of the organisation at its offices in Vauxhall,[1][2] responsible to a board which included Reed, Nandy, Cruddas and Chinn.

A document sent to prospective donors warned that the "Hard left [...] will divide our party, condemn us to electoral defeat, attempt to drive out democratic socialists and corrupt our moral purpose in the interest of ideological aims".

These donations were not declared and the group claimed not to back any candidate until after 2022, at which point its public statements began to state that it "played a key role in Keir Starmer’s leadership campaign."

"We intentionally designed our review so that our whole movement can feel part of it, because the process of constructing a project that involves all our traditions is as important as what we conclude.

[16][17] In 2022, Josh Simons, a former Corbyn policy advisor who had resigned in protest due to accusations of antisemitism in the party, took over as director of the group.

[1] A report from the group on 29 March 2023, one of its first major attempts at profiling the full British electorate, identified the "Stevenage woman" in addition to the "Workington man" as critical to a Labour election victory.

"[2][21] As of October 2023 Labour Together had received over £1.8 million in donations after Starmer became leader, with the three biggest donors being Martin Taylor, Trevor Chinn and Gary Lubner.

[1] In October 2023, Politico noted that "nearly all the MPs credited with building Labour Together since 2017 — Reeves, Wes Streeting, Shabana Mahmood, Steve Reed, Bridget Phillipson, Lucy Powell and Lisa Nandy — now sit in Starmer’s top team.

"[22] It has published policy papers on investment, technology, artificial intelligence, climate, constitutional reform, and geopolitics, which include China.

[25] At the 2024 general election, five staff or policy fellows (Josh Simons, Miatta Fahnbulleh, Hamish Falconer, Chris Curtis, and Gordon McKee) became Labour MPs.
