U.S. President Donald Trump is expected to disclose details of his Middle East peace plan to Israeli leaders on Monday as Palestinian officials decried it as a bid "to finish off" the Palestinian cause. 

Trump will meet separately with right-wing Israeli Prime Minister Benjamin Netanyahu and centrist opposition leader Benny Gantz in Washington over his long-delayed proposals, which have been kept secret. 

Palestinians fear the plan will dash their hopes for an independent state in the West Bank, East Jerusalem and the Gaza Strip. Palestinian leaders say they were not invited to Washington and that no peace plan can work without them.  

Trump was impeached in the House of Representatives last month and is on trial in the Senate on abuse of power charges. Netanyahu faces corruption charges and a national election on March 2, his third in less than a year. Both men deny wrongdoing. 

Trump's initiative, whose principal author is his son-in-law Jared Kushner, follows a long line of efforts to resolve one of the world’s most intractable problems. 

Trump hoped to release his own plan last year but was forced to delay as Netanyahu twice tried unsuccessfully to form a governing coalition after inconclusive elections. 

After Monday's meetings with Netanyahu and Gantz, Trump will on Tuesday deliver joint remarks with Netanyahu at the White House, where the president may reveal details of his proposal. 

But whether it truly will jumpstart the long-stalled effort to bring Israelis and Palestinians together is far from certain. 

Palestinian PM calls on world to boycott Trump peace plan 

Palestinian Prime Minister Mohammed Shtayyeh on Monday urged international powers to boycott Trump's "peace plan" which they see as biased towards Israel. 

"This is a plan to protect Trump from impeachment and protect (Israeli Prime Minister Benjamin) Netanyahu from prison. It is not a Middle East peace plan," Shtayyeh told a cabinet meeting. 

"This plan gives Israel sovereignty over Palestinian territory," he said. 

"We call on the international community to not be partners in this because it contravenes international law," Shtayyeh told the Palestinian cabinet. 

"The rights of the Palestinian people are not for sale."
