"Hannity & Colmes," the longest-running program on the Fox News Channel, will soon be without Colmes.
Alan Colmes, 58, the liberal half of the 9 p.m. show, will leave his daily hosting duties at the end of the year, the network announced Monday.
While the network remained quiet about its plans for the political debate program, two people close to the network said that Sean Hannity, 46, Mr. Colmes's conservative counterpart for the last 12 years, would become the sole host of the hour. The people requested anonymity while speaking about private deliberations.
Mr. Colmes's departure, coming as a Democrat prepares to take over the White House, is a sharp change to the prime-time lineup of Fox News, a subsidiary of the News Corporation. A Fox News spokeswoman would not confirm that Mr. Hannity would be the sole host.
