Kwarteng is sticking to his guns on tax and spending cuts. But what he really needs is luck

The chancellor appears unwilling to reverse any of the measures in his mini-budget. If he is to survive, it may be down to factors beyond his control

Kwasi Kwarteng's inept handling of the government's finances since he took office last month has left Liz Truss cornered. The prime minister must play for time and piece together a rescue plan by the end of November, along with a more rounded budget that preserves her tax-cutting agenda while also appearing responsible to financial markets watchful for the next misstep.

Treasury officials, rudderless after the departure of two permanent secretaries (Tom Scholar and deputy Charles Roxburgh) in the space of four months, will be under pressure to find a formula that also satisfies the cautious instincts of the government's independent economic forecaster, the Office for Budget Responsibility (OBR), which is inclined to dismiss policy quick wins" as ineffectual until evidence proves otherwise.
