Morgan McSweeney, who served as Keir Starmer’s chief of staff, has resigned amidst a controversy involving alleged plots against the Prime Minister, signifying the increasing internal strain within the Labour Party. McSweeney was a key strategist behind Starmer's rise to leadership, especially following the defeat during Jeremy Corbyn's tenure, and his departure raises questions regarding the stability of Starmer's leadership amidst ongoing pressures from party factions. The tensions heightened after a miscalculated briefing by No 10 which was aimed at solidifying Starmer's position but instead ignited anger from key officials like health secretary Wes Streeting. McSweeney’s exit, along with other senior staff departures, signifies a tumultuous period for Labour, highlighting the internal struggles as the party seeks to redefine itself in the political landscape of the UK after recent electoral setbacks.
