The survey was disclosed as Benjamin Netanyahu, the incoming prime minister, presented himself as a peacemaker and assured Palestinians that his government would be their "partner".
Even as Mr Netanyahu was addressing the conference, however, Israel's Army Radio reported that he had agreed to build more homes inside Jewish settlements on the West Bank inside an area known as E-1, a few miles east of Jerusalem. Construction in this vital region could sever the West Bank in two, making the creation of a viable Palestinian state even more difficult.
The radio station said this was part of a secret agreement with Avigdor Lieberman, the leader of the nationalist Yisrael Beitenu party, who is likely to be foreign minister in the new coalition.
