JERUSALEM – In a stinging rebuke, Prime Minister Sharon’s party voted today to bar him from adding the opposition to his government to bolster his Gaza pullout plan, Israel Radio reported.

But Mr. Sharon had earlier sent a signal that he would ignore such a result, telling his party’s convention before the vote that he would not accept any disqualifications or boycotts.

The vote was about 60% for banning the moderate Labor Party, the radio reported. Mr. Sharon’s own proposal, to allow him to negotiate with all the Zionist parties, was narrowly voted down, Israel Radio said.

The vote against Mr. Sharon was similar to the result of a referendum on the pullout plan itself on May 2 among party members.

In that nonbinding vote, about 60% of Likud Party members voted against the “unilateral disengagement” plan – removing all 21 settlements from Gaza and four of the 150 from the West Bank.

Labor strongly favors Mr. Sharon’s “unilateral disengagement” plan, as Labor has long advocated an Israeli pullout from Gaza and most of the West Bank for peace with the Palestinian Arabs.

“The vote here today is not for or against the disengagement plan,” said critic Michael Eitan during his earlier speech, but the clear subtext of the rebellion was an attempt to scuttle the pullout.

After his May 2 defeat, Mr. Sharon said he would honor the vote, but he changed his mind and rammed it through his Cabinet. But in the process, he had to fire a pro-settlement coalition partner and weather resignations of another Cabinet minister, losing his parliamentary majority.

Adding Labor would cement his Cabinet majority for the plan and give him clear control of the Parliament, and Likud critics were trying to prevent that at yesterday’s meeting.

Opponents to Labor’s joining the government were the same Likud members who reject the disengagement plan.
