Across many countries, civil services, once seen as the backbone of stable governance, are facing growing scrutiny. Long viewed as the impartial and efficient machine of government, the role of civil servants is now being questioned as political polarisation intensifies and trust in traditional institutions declines.

In the UK, the United States and other democracies, critics question its effectiveness, arguing that the civil service has become opaque, unwieldy and inefficient, and process is getting in the way of outcomes.

The modern British civil service emerged in the 19th century, and was designed to carry out the day-to-day tasks of government in an unbiased and professional manner.

However, is a bureaucracy that was created and designed more than a century ago still fit for purpose - or are we witnessing a turning point in its role in modern governance?
