Israel's parliament swore in its new unity government led by Prime Minister Benjamin Netanyahu and his former rival Benny Gantz, ending the longest political crisis in the nation's history. 

Politicians in the 120-person parliament, the Knesset, formally approved the three-year coalition government with 73 voting for and 49 against. One member was absent for the vote. 

Addressing the Knesset before the vote, Mr Netanyahu vowed to push on with controversial plans to annex large parts of the occupied West Bank.

He said his incoming government should apply Israeli sovereignty over West Bank settlements.

"It's time to apply the Israeli law and write another glorious chapter in the history of Zionism," Mr Netanyahu said on the issue of Jewish settlements in the occupied Palestinian territory.

Such a move is seen likely to cause international uproar and inflame tensions in the West Bank, home to nearly three million Palestinians and some 400,000 Israelis living in settlements considered illegal under international law.

Mr Netanyahu told the chamber that annexation "won't distance us from peace, it will bring us closer".

Israel's unity government starts work amid the coronavirus pandemic and after a political crisis that saw three inconclusive elections and left the country in political limbo for more than 500 days.

The coalition government was agreed last month between Mr Netanyahu, a veteran right-wing leader, and Mr Gantz, a centrist former army chief.

Plans had been set for an inauguration last Thursday, but after 17 months without a stable government, Mr Netanyahu asked for three more days to decide on cabinet assignments among his Likud party loyalists. 

Under the three-year coalition deal, Mr Netanyahu will serve as prime minister for the coming 18 months - a major victory for a leader due to stand trial in a week on corruption charges, which he denies. 

Mr Gantz will be alternate prime minister, a new position in Israeli governance, for the first half of the deal, before he and Mr Netanyahu swap roles.

The new government's policy guidelines state as top priorities combatting the coronavirus and healing an economy battered by the pandemic. 

The new government may be confronted with yet another international crisis in matter of weeks, centred on the West Bank. 

The Netanyahu-Gantz deal says the government can from 1 July 1 initiate moves to implement US President Donald Trump's controversial peace plan for the Israeli-Palestinian conflict. 

The plan, rejected by the Palestinians, gives the green light from Washington for Israel to annex Jewish settlements and other territory in the West Bank. 

Some experts warn that Jordan may back away from its historic 1994 peace deal with Israel if the Jewish state tries to annex the strategically crucial Jordan Valley border region. 

Speaking to German magazine Der Spiegel days ago, Jordan's King Abdullah II said: "If Israel really annexes the West Bank in July, it would lead to a massive conflict with the Hashemite Kingdom of Jordan."

The European Union's foreign policy chief Josep Borrell said Friday that the bloc would use "all our diplomatic capacities" to try to dissuade Israel's incoming government from going ahead with annexations. 

Mr Gantz and incoming Foreign Minister Gabi Ashkenazi are both known to have reservations about annexation and the international backlash.

Mr Gantz did not mention the issue in his Knesset speech.

He addressed criticism of his move to join forces with Mr Netanyahu, which split his Blue and White coalition, arguing that Israel needed unity after a year of bitter division.

"My friends and I chose unity to defend Israeli citizens, not just from the challenges from outside our borders but also from the hatred eating away at us from within and harming our resilience," he said.
