edam in summary, IT guy at Telegraph nabs audio files and gives them to Will Lewis at NI. He is rewarded with a new job at NI on an unusually large salary.
WL knows that if they get the story out, it will put the kibosh on Vince being in charge of the Sky decision and potentially ensure someone more malleable is put in his place. Obvs NI titles can't scoop the story themselves as everyone will know they are leaking it to get sympathy and get Cable off their backs
SO instead, WL passes it to swedishcheff pesto who goes "Oh, scoop, thanks for that" and runs with it... his reward is recognition for another exlcusive....
