Embattled Chancellor Kwasi Kwarteng has admitted to losing sleep over the financial turmoil that followed his mini-Budget.
Mr Kwarteng accepted that the bombshell blueprint for £45bn in tax cuts funded by borrowing had been done "at very high speed" but he was convinced it was the right plan.
Liz Truss and Mr Kwarteng are pressing ahead with their tax-cutting blitz despite disruption in the markets, which saw the pound slump against the dollar and forced the Bank of England to make an emergency £65bn intervention to prevent a run on pensions.
