The Israeli prime minister Benjamin Netanyahu has voted in the country’s general election, fighting to stay in office for a fourth term.

He cast his ballot at a school in Jerusalem, vowing to form what he calls a “national government” – meaning right wing – and that there’ll be no union with the left.

The last opinion polls gave a slight lead to the Zionist Union party of Netanyahu’s centre-left rival Isaac Herzog.

But under Israel’s system all will depend on which party can garner enough support to form a coalition.
