“Corrupt actors hide their money in the United States all the time. We can no longer provide them a shadow under which to operate,” wrote the treasury secretary, Janet Yellen, and the USAID administrator Samantha Power in an article announcing the strategy. “Combating corruption abroad, therefore, begins at home, and our first step must be to expose the owners of shell companies and other illicit funds.”In contrast to that, Truss failed to satisfactorily answer a question from the audience on the British role in laundering money after her speech at Chatham House, choosing instead to talk about how we shouldn’t talk about the empire. If she’d only hung around until after lunch, however, she would have realised quite how colossal her omission was, since on Wednesday Chatham House also hosted the launch of a major report by a group of academics that forensically dissected Britain’s role in enabling corruption, and came to conclusions that were all the more alarming for the sober language they were described in.
