What was billed as a small tweak to Boris Johnsons Cabinet has turned into the most significant moment in British politics since at least the election, and perhaps even the referendum. With Sajid Javid resigning as Chancellor and Mr Johnson ensuring that his successor, Rishi Sunak, is firmly within the control of No10, several decades of Whitehall orthodoxy appear to have been overturned.

As ever, our politics team offers unrivalled coverage and insight into the events shaping British politics. Camilla Tominey has the inside story of Mr Javids brief stint as Chancellor, detailing how the relationship started on the wrong foot and deteriorated from there. Fraser Nelson explains what was at stake, why the reshuffle leaves Mr Johnson in total control and reveals the true ambitions of his and Mr Cummingss Whitehall overhaul. Meanwhile, Anna Mikhailova profiles Mr Sunaks lightning rise to the top and how his financial background has shaped his politics.
