On Monday night, Liz Truss was holding forth at a victory party on the rooftop of Deliveroo’s headquarters in Cannon Street, before leaving early to prepare for her audience with the Queen the next day. Thérèse Coffey, her soon-to-be deputy prime minister, hit the dance floor along with aides.
Little did they know that their sense of jubilation was to be shortlived. With just hours of experience as prime minister behind her, Truss has found herself leading the nation through a period of mourning following the death of the Queen on Thursday afternoon.
