The Liberal insider who tried to funnel donations from an alleged Mafia boss to help Victorian Opposition Leader Matthew Guy win this year’s state election is still an active party member – despite earlier suggestions that he would “move on”.

Nine months after The Age exposed a dinner involving Mr Guy and Melbourne businessman Tony Madefferi at the Lobster Cave in Beaumaris, the man who organised that meeting, former Liberal official Barrie Macmillan, remains a key figure within party ranks.

The revelations are likely to prove sensitive for Mr Guy and the Liberal Party, which sought to distance itself from Mr Macmillan in the wake of the so-called "Lobstergate" scandal.

“I think he will move on, and I think that will be the right thing to do,” the Opposition leader said in August.
