Was Andreotti actually a MEMBER? I know he was thoroughly in collusion with the mafia, like Dell Utri and to an extent Berlusconi but he wasn't an actual member, was he?

Makes me wonder, what's the highest an actual mafioso has risen in front line politics? Obviously they've managed to infiltrate Italian politics to the highest level at various times, but what about actual mafioso politicians - and I mean outside the countless members on town/village councils in rural Sicily and Calabria.
