ALBANY – The one-time leader of New York’s Liberal Party pleaded guilty yesterday to a felony for accepting $800,000 in state pension-fund investment fees in return for his political support of former state Comptroller Alan Hevesi and Mr. Hevesi’s son during an election for Assembly.

Raymond Harding faces up to four years in prison for the state securities law violation. In addition, he has lost his license to practice law, although Attorney General Andrew M. Cuomo held out the possibility that he could regain it once the case is over.
