The executive secretary of the Financial Action Task Force has resigned his position while raising questions about the ability of the intergovernmental group’s secretariat to operate independently.

In a Sept. 23 letter obtained by ACAMS, David Lewis, who has served as the global anti-money laundering standard setter’s most senior official since November 2015, informed staff that he was stepping down after six years in the role despite the unanimous agreement by members to renew his three-year contract for a second time.
