Israel has warned that Iran is close to getting its hands on a nuclear bomb.
And the West must face the growing threat of the regime becoming a nuclear power, Prime Minister Naftali Bennett added.
He told the Telegraph: “Iran is enriching uranium at an unprecedented rate and is dangerously close to acquiring its own nuclear weapon.”
The state is thought to have enriched uranium to more than 60%, providing enough material to make a bomb.
Its capital Tehran denies building nuclear weapons.
But Bennett urged Britain to maintain pressure on its leaders.
It is alleged that Israel asked Britain to consider the tripartite mechanism as a further deterrent against Iran. It will deal a bigger blow to Iran.
Mr. Bennett added: “Without Western pressure, the Islamic regime in Iran could soon get a nuclear bomb.
“The world must take a firm stand and say to the Islamic regime in Iran: no nuclear weapons, no sanctions.
“Iran’s nuclear program will not stop until it is stopped.”
Iran restarted its nuclear program when President Donald Trump pulled out of the nuclear deal in 2018.
Negotiations to restore the deal have stalled.
And Western diplomats are giving up hope of resurrecting it because they believe the regime is building a bomb, Israeli officials believe.
The United Nations atomic agency said this week Tehran was not cooperating with investigations into its nuclear program.
It turned off at least two of the agency’s surveillance cameras to monitor nuclear sites.
Last August, it was feared that Iran was ten weeks away from having a nuclear weapon.
It comes as the new hardline President Ebrahim Raisi, nicknamed the Butcher of Tehran for his harsh punishments, is sworn in as leader.
