Leadership instability increases UK borrowing costs and wastes public funds

Former Cabinet Secretary Simon Case warned lawmakers today that the UK’s frequent leadership changes have significantly increased government borrowing costs and disrupted long-term planning.

Case, who served as the country's top civil servant, noted that financial markets demand higher interest rates—a "risk premium"—when political direction is unclear. This "uncertainty tax" directly drains the public treasury, leaving less money for essential services like healthcare and infrastructure. He highlighted that the rapid turnover of prime ministers and ministers makes it nearly impossible for civil servants to execute complex, multi-year policies effectively.

Government watchdogs are now expected to investigate whether new administrative safeguards could provide more continuity during future periods of high political volatility.
