The United Kingdom has no equivalent to the FBI’s International Corruption Squad or the Department of Justice’s Kleptocracy Team. The City of London has a small financial crimes unit, but it lacks the resources and political heft of the Southern District of New York when it comes to perp-walking the perpetrators of financial malfeasance. Yet London’s stock exchange moves more money than New York’s, and buying a home in London will cost you nearly twice as much per square foot as buying in New York.
