Some 31% of the poll's respondents said they do not support the annexation plan, while the remaining 21.7% answered they don’t know.
The poll also found that a vast majority of French-speaking Israelis (90%) support an annexation of parts of the West Bank, highlighting a difference of political attitudes towards the Israeli-Palestinian conflict between the two communities of Olim (immigrants to Israel).
The poll consisted of 464 native English-speaking and French-speaking Israelis aged 18 years and older.
The growth of the French Jewish community in Israel has come as a consequence of well-publicized incidences of antisemitism in France, often violent, in addition to ISIS terrorist attacks there that have targeted Jews in recent years.
Conversely, English-speaking immigrants to Israel are far less likely to attribute antisemitism as the driving force behind their move, with many often citing ideological or religious motivating factors.
Earlier on Monday, Prime Minister Benjamin Netanyahu repeated his intention to apply Israeli sovereignty in select areas of the West Bank, including the Jordan Valley and some Israeli settlements.
Palestinian Authority President Mahmoud Abbas and Jordanian King Abdullah have both strongly opposed any Israeli annexation proposal, threatening serious political and security ramifications in the event of such a move.
