It's no secret that Labor joined Prime Minister Ariel Sharon's coalition to support the evacuation of Jews from Gaza and northern Samaria. Now that the withdrawal has been completed, the left-wing Labor party feels obliged to leave the government and resume its position as an alternative to the present administration. Though a date for general elections hasn't yet been set, Labor has plenty of work within its own party to prepare for the race. "We said we were coming to…assist Ariel Sharon in implementing the disengagement," Labor's Secretary General and Member of Knesset (parliament) Eitan Cabel told Israel Radio this morning. He also said that his party would try to reach an agreement on a date for the elections before leaving the government.
