DEVELOPING: Starmer's chief of staff McSweeney defies speculation, remains in role.

Breaking News: McSweeney to Remain as Starmer's Chief of Staff Sir Keir Starmer's chief of staff, Morgan McSweeney, will not be leaving his role despite speculation over his involvement in recent briefing wars. Sources close to the BBC confirm McSweeney was not directly or indirectly involved in the briefings. McSweeney's decision to stay comes as Starmer faces calls to sack those responsible for the briefings, which have caused turmoil within the government. The briefings, which included claims of a potential leadership challenge from Health Secretary Wes Streeting, have been blamed on McSweeney by some in government. The controversy began on Tuesday when allies of Prime Minister briefed journalists that he would take on any challenge to his leadership. Government sources have since sought to draw a line under the affair, with some attempting to shift the blame onto McSweeney. For now, McSweeney remains in his position, with sources close to him insisting he has done nothing wrong. This is a developing story, and we will continue to provide updates as more information becomes available.
