Israeli opposition parties have just hours left to form a new government that would end Benjamin Netanyahu’s 12-year stretch as prime minister.
Yair Lapid of the centrist Yesh Atid party has made several deals ahead of the midnight (21:00 GMT) deadline.
But crucially he is yet to reach a final agreement with the right-wing nationalist politician Naftali Bennett.
Mr Bennett is expected to become the prime minister ahead of Mr Lapid under a rotation arrangement.
Mr Netanyahu and his Likud party have been appealing to fellow right-wing politicians not to join the coalition, knowing that a new government would still face a vote of confidence in parliament before it could be sworn in.
If it fails to win the support of a majority in the 120-seat Knesset, there is a risk of the country having to go to elections for the fifth time in two years.
