With Osama bin Laden dead, Iran's supreme leader is the biggest threat to global security, Binyamin Netanyahu said in an interview today.
The Israeli Prime Minister told CNN that Ayatollah Ali Khamenei was more of a threat than Iran's President Mahmoud Ahmadinejad.
Speaking on the final day of his visit to London Mr Netanyahu said: "He runs the country and he is infused with fanaticism. If the Iranian regime gets atomic bombs, it will change history.
"The future of the world - the future of the Middle East - is certainly at stake."
