Togo West Jr., chairman of the D.C. Board of Elections and Ethics, is resigning, according to city officials.

Mayor Vincent C. Gray (D) said West’s departure was “his choice.”

“It certainly wasn’t mine,” Gray said, praising West’s tenure.

Gray said he has a replacement in mind, but did not want to elaborate on his possible choice. West, a former secretary of the Army and of Veterans Affairs, was appointed to the board last year by former mayor Adrian M. Fenty.

West’s resignation follows the recent departure of the board’s executive director, Rokey Suleman. The elections board plans to replace him with a permanent director by Labor Day. West and Suleman did not return calls seeking comment.

The departures come as the city begins to prepare for next year’s local primary elections, which are being held in April.

“I’m certain that we will be ready for the election next year,” Gray said.
