The chairman of the District’s alcohol control board resigned Friday, a year before his tenure expired, Mayor Vincent C. Gray’s office confirmed Saturday.

Gray (D) has said he did not intend to reappoint Charles Brodsky.

Charles Brodsky, named head of the Alcoholic Beverage Regulation Administration by former Mayor Adrian M. Fenty (D), did not offer an explanation for his resignation, mayoral spokeswoman Doxie McCoy said.

Board member Nicholas Alberti will stand as interim chair until Gray selects a full-time replacement, McCoy said.

Brodsky had been accused by a former board member of conflicts of interest, according to the Washington Examiner, which first reported his resignation.

Brodsky has denied the allegations and Gray’s office has not found wrongdoing.
