Treasury objections and government responsibility

Could the Crown order the Treasury to comply with government policy?

The answer allows it theoretically, but stresses that the prime minister appoints the chancellor and that Treasury objections do not remove the government's responsibility for its decisions.

Royal intervention is accepted only as a theoretical possibility before the answer turns to political responsibility. The prime minister appoints the chancellor, so a Treasury objection is also a dispute within the government. The criticism is that blaming the Treasury can excuse abandoning promises presented to voters as fully costed. This is compared with earlier British political arguments that blamed the European Union for undelivered policies. Repeated use of that explanation is expected to encourage demands to break up the Treasury.
