Karie Murphy is a British trade unionist and political strategist who served as the Executive Director of the Leader of the Opposition's Office under Jeremy Corbyn from 2016 to 2020.
[4][5] Along with Seumas Milne, Andrew Murray and McCluskey, she has been identified as one of the "Four Ms" who it is claimed had significant influence on Corbyn's leadership of the Labour Party.
[6] In the 2017 general election, it was the Labour leadership's office team, led by Murphy, that was credited with the foresight to approach the poll in ways barely understood by most media commentators at the time, resulting in a hung parliament.
[10] Sources in The Times newspaper criticised the failure to provide resources to internal Corbyn critics such as Ruth Smeeth, Mary Creagh, and Melanie Onn,[10] as well as the decision to target seats such as Finchley and Golders Green where former Labour MP Luciana Berger was running, and Plaid Cymru-held Arfon[10] instead of Conservative-Labour marginals in nearby Aberconwy and Clwyd West.
[14] In 2021, McCluskey wrote in his autobiography that he used funds from the Unite trade union, of which he was then leader, to pay libel lawyers to prevent the press from publishing that he and Murphy were in a romantic relationship even though they were.
