An Israeli official says Prime Minister Benjamin Netanyahu wants the fate of the West Bank included in a referendum on any land-for-peace deal with the Palestinians.

Current law only requires a referendum if Israel gives up east Jerusalem or the Golan Heights, war-won lands it annexed.

It’s unclear if adding the West Bank would make it harder for a deal to get approved or if Mr. Netanyahu wants a wider political cover for negotiations.

An official in Mr. Netanyahu’s office, on condition of anonymity, said on Wednesday that the prime minister asked for an amended referendum bill to include the West Bank.
