Dominic Perrottet’s ties to one of the decade’s biggest political scandals likely remain hidden from voters until after March election.

Guide Dogs Victoria’s board – which claims to have been unaware of political spruiking by its ousted CEO Karen Hayes – was alerted to serious concerns of similar activity almost decade ago.

The general manager responsible for communications at Guide Dogs Victoria has left the embattled group, along with its chief financial officer.

The Administrative Appeals Tribunal made over 1,200 illegal payments to unnamed senior officials.

At least seven top public officials have been allegedly illegally paid for holding two jobs at the same time - department bosses told “seek legal advice”.
