The report has subsequently been denied by the Palestinian Authority and the White House – with the Saudi government also insisting they would not support these positions.
But there is speculation that the Saudi Crown Prince has deliberately unveiled a worst-case scenario for the Palestinian leadership so that they can make a forthcoming official offer seem generous in comparison.
The White House has been completing what has become known as the “ultimate deal” for the region over the past year, with Mr Trump’s son-in-law Jared Kusher at the forefront alongside other aides.
In an appearance at a Middle East conference in Washington on Sunday, Mr Kushner said: “We know what’s in the plan.
“The Palestinians know what discussions we’ve had with them. The Israelis know what discussions we’ve had with them.”
But a White House spokesperson said a report on the details of the plan was “speculation”.
