Israel apologises over threats to 'take down' UK minister
The Mail on Sunday newspaper posted the footage showing the embassy's senior political officer Shai Masot telling an undercover reporter from Al-Jazeera television: "I want to take down... the [UK] Deputy Foreign Minister [Alan Duncan]."
Duncan, Foreign Secretary Boris Johnson's second-in-command - and a long-time critic of Israel - was "doing a lot of problems", he added.
Duncan once described Israeli settlements in occupied Palestinian territories as a "stain on the face of the globe", calling them an "act of theft".
"Occupation, annexation, illegality, negligence, complicity - this is a wicked cocktail which brings shame on Israel," he told the BBC in 2014.
Masot also called Johnson an "idiot" and mocked "crazy" opposition Labour leader Jeremy Corbyn and his "weirdo" supporters.
The embassy issued an immediate apology, saying it "rejects the remarks concerning minister Duncan, which are completely unacceptable".
"The comments were made by a junior embassy employee -who is not an Israeli diplomat - and who will be ending his term of employment with the embassy shortly," it added.
Ambassador Mark Regev apologised personally to Duncan on Friday, according to the embassy.
The UK's foreign office confirmed it had received an apology, and that it now considered "the matter closed".
'A little scandal?'
The incident comes amid an Israeli diplomatic offensive against countries which backed a UN resolution last month demanding a halt to settlement building on Palestinian land.
All 15 members of the UN Security Council - including permanent member the UK - voted in favour of the resolution except for the US which abstained rather than wielded its veto, sparking Israeli fury.
It was not immediately clear if Masot's comments were linked to the resolution.
Conservative chairman of the Foreign Affairs Select Committee Crispin Blunt told the Mail on Sunday the comments were "outrageous".
The footage was recorded at a restaurant opposite the Israeli embassy in London's upmarket Kensington district, during a meeting attended by Maria Strizzolo, senior aide to Conservative Education Minister Robert Halfon.
Strizzolo spoke of her influence in helping Halfon become a minister, prompting Masot to ask her: "Can you do the opposite stuff as well?"
However, Strizzolo said Duncan would be "impossible to rebuff" due to having powerful "friends", but then suggested "a little scandal, maybe?"
Strizzolo told the newspaper that she was speaking to Masot as a friend and that the conversation had been "tongue-in-cheek and gossipy", adding: "Any suggestion that I ... could exert the type of influence you are suggesting is risible."
