Denmark has maintained its position at the top of the rankings since 2021 and even increased its CPI score from 88 to 90. The nation is lauded the world over for its low levels of corruption. However, as we've seen, even the most virtuous countries have their faults.

Indeed, one of the world's biggest known money-laundering schemes involved a Danish bank, when around €200 billion ($243bn/£175bn) of suspicious money passed through the Estonian branch of Danske Bank between 2007 and 2015. The bank has also been accused of helping Germany's Deutsche Bank to pass more than $600 million (£433m) in suspicious trades through Danske Bank branches in Lithuania over the same time period.

These scandals were allegedly helped along by Denmark's inadequate financial regulation. Although regulations have since been tightened, the nation's anti-bribery laws remain limited. In fact, Transparency International has downgraded Denmark's foreign bribery rating to "little or no enforcement" in the latest report.
