@Obscure_Rebel wasn’t aware of this:

Hersh alleged Davies specifically betrayed #Vanunu’s location, while #Maxwell was implicated as having #Mossad ties and playing a supporting role. Both allegations were disputed but never fully resolved in court - the #Mirror ultimately apologized to Hersh rather than continue the legal battle.​​​​​​​​​​​​​​​​

[…] A bitter, protracted dispute between a British newspaper group and prominent investigative reporter Seymour Hersh came to a quiet finish in a London courtroom yesterday when the Mirror Group apologized to Hersh for its "attempts to impugn" his integrity and agreed to pay "substantial damages."

[…] In it, Hersh reported that the paper's owner, publishing tycoon Robert Maxwell, and its foreign editor, Nicholas Davies, had links to the Israeli intelligence agency Mossad.
