Israel's parliament on Monday passed a law calling for a national referendum ahead of any withdrawal from annexed east Jerusalem or the Golan Heights, a move that could derail future peace deals, AFP reported.
The law, which had the backing of Prime Minister Benjamin Netanyahu, passed with 65 lawmakers in favour and 33 against in a late night vote. There were no abstentions.
Under the new legislation any government signing a peace agreement ceding the annexed territories of east Jerusalem or the Golan, or any other sovereign territory within Israel itself, would be unable to implement the treaty without the approval of parliament and a national referendum.
It would not affect territorial concessions within the West Bank or the Gaza Strip, which Israel has not annexed.
Netanyahu, who is currently engaged in efforts to revive stalled peace negotiations with the Palestinians, praised the passage of the law.
"Any peace agreement demands a broad national agreement and this law provides this," a statement from his office said after the vote.
"The Israel public is involved, informed and responsible and I trust that on the day of decision they would back a peace agreement that answers the national interests, security needs of the State of Israel," he said, according to the statement, Press TV reported.
