In a first for the U.S. Department of Justice, the agency is sending an anti-corruption prosecutor to work in a U.K. agency on white-collar crime.

Acting principal deputy assistant attorney general Trevor McFadden, in remarks prepared for a May 24 speech in Brazil, said it was part of the DOJ's growing cooperation with foreign prosecutors.

The secondment includes one year at the U.K.'s Financial Conduct Authority and one year at its Serious Fraud Office.
