Olmert's centrist Kadima Party slid slightly in opinion polls published Thursday, five days ahead of a general election, but still held a commanding lead over other parties.

"I want to emphasise so that no one doubts it: I intend to implement this plan. Anyone who is not interested in seeing this plan implemented will not be in my coalition. I do not intend to compromise on the details of the plan. This is the plan and there is no other," Olmert said.

Olmert has said that if he is elected he would dismantle most West Bank settlements, fortify remaining settlement blocs and set the nation's borders by 2010. The blueprint is the most detailed proposal for Israel's borders ever presented to voters by an Israeli leader.

Olmert told Channel 10 television on Wednesday that he would wait some time if he is elected before implementing the withdrawal plan to see if Hamas which swept a January Palestinian parliamentary election will moderate its militant views and negotiate with Israel.

But if Hamas refuses to recognise Israel, accept past Israeli-Palestinian peace agreements and renounce violence, Israel will move to unilaterally draw its borders, Olmert said.

Kadima was founded by Prime Minister Ariel Sharon weeks before he suffered a massive stroke on Jan. 4 that left him comatose. Olmert stepped into Sharon's position, and is being viewed as his successor.
