The UK government also has an excellent civil servant corps. In reality it’s the civil service, that continues across government, that keeps the UK govt running. The elected officials are limited to providing high level directions.
One of the major mistakes made by Kwarteng as chancellor was firing an extremely senior civil servant which spooked not just the civil service but also the markets, because it indicated that elected officials would now be more active in running the business of government. That’s something no one really wants.
