Sir Keir Starmer has announced he is standing down as Prime Minister. In this emergency episode of Whitehall Sources, Calum Macdonald, political strategist Jo Tanner, and former No. 10 deputy policy chief James Nation take you inside the room for one of the most shocking days in modern Westminster history.

How did Starmer’s authority evaporate just two years into his premiership? From the catastrophic fallout of the budget and the Mandelson affair to the historic Makerfield by-election victory, we break down exactly why the game was up for Starmer.

Plus, we look at the incredible visuals of Andy Burnham’s arrival in Westminster. With over 200 Labour MPs rushing to be in his selfie, power has officially shifted. Is a Burnham coronation inevitable? What does a Burnham government mean for the economy, devolution, and the markets? And what is it actually like inside Number 10 when a Prime Minister resigns?
