New York City Deputy Mayor Edward Skyler will leave his position at the end of April to help oversee communications both with investors and government at banking giant Citigroup Inc.

Skyler will lead all external and internal communications and share leadership of government affairs and investor relations within his newly created post. The U.S. government owns a nearly one-fourth stake in Citi.

The company said Skyler, who has been a member of New York City Mayor Michael Bloomberg's administration since the billionaire was first sworn in eight years ago, will join the company in early May.

Skyler had worked in the corporate communications group of Bloomberg LP -majority owned by Bloomberg - before joining his campaign for mayor as its press secretary. He also oversaw four city budgets, negotiated legislation to reform lobbying and "pay-to-play" practices and helped reach agreements with labor unions to reduce pension and health costs, Citi said in a statement Tuesday.

Shares were recently down 2.4% to $4.07 amid a broad decline in the financial sector.
