Jonathan Powell, currently serving as Keir Starmer's national security adviser, has turned down proposals to fill the chief of staff position after Morgan McSweeney's resignation. Sources reveal that Powell's decision is influenced by his desire to return to the mediation consultancy he founded in 2011, rather than stepping back into a role he previously filled under Tony Blair's premiership. While Powell considers leaving his role at Downing Street by the end of the year, such a move would mark another significant change within Starmer's senior team.

Downing Street officials have denied any claims that Powell is preparing to leave his current role or that he was ever formally offered the position of chief of staff. These denials suggest that Powell's influence as national security adviser remains strong, and his commitment to that role is intact for now. This denial from Downing Street adds to the ongoing speculation about the stability and composition of Starmer's senior team, especially in light of recent changes including McSweeney's resignation.

The situation raises questions about the future direction of Starmer's leadership and whether Powell's choice to remain as national security adviser rather than step into a more political role could impact the government's approach to national security and international relations. The emphasis on Powell's consulting firm indicates a preference for a less political and more strategic role, potentially shaping the way the Labour Party positions itself on security issues moving forward.
