The longtime executive director of enforcement and market oversight at the U.K. Financial Conduct Authority (FCA) announced his intention to step down.

Mark Steward will depart the FCA in the spring after seven years with the regulator. Steward joined the FCA in 2015 from the Hong Kong Securities and Futures Commission, where he was executive director with responsibility for the Enforcement Division.

In addition to overseeing enforcement at the FCA, Steward has led the regulator’s listing authority and oversight of the U.K.’s publicly traded markets, a role in which he developed the FCA’s data-led approach to market oversight. Additionally, he has been at the forefront of the FCA’s anti-scam marketing campaign.

The global search for Steward’s successor will begin shortly, the regulator announced.
