Mossad allegations; Vanunu case edit
The Foreign Office suspected that Maxwell was a secret agent of a foreign government, possibly a double agent or a triple agent, and “a thoroughly bad character and almost certainly financed by Russia”. He had known links to the British Secret Intelligence Service (MI6), to the Soviet KGB, and to the Israeli intelligence service Mossad.[57] Six serving and former heads of Israeli intelligence services attended Maxwell’s funeral in Israel, while Israeli Prime Minister Yitzhak Shamir eulogised him and stated: “He has done more for Israel than can today be told.”[58]
Six heads of Mossad and an ex-prime minister of Israel were in attendance at his funeral, and he is also known to have taken money from Russia for his services.
