FORMER first bloke Tim Mathieson has threatened Victorian Premier Denis Napthine with legal action in a furious phone message that ends with him saying “Bang!”

The tirade, obtained by The Sunday Telegraph, was recorded after Mr Mathieson called the Premier’s Warrnambool electorate office after hours and got the answerphone.

In a 32-second message, Mr Mathieson complains the Premier, who worked as a veterinarian before entering politics, had mentioned him in Parliament in connection with rogue MP Geoff Shaw’s misuse of his taxpayer-funded car.

“Of course you’re busy ­because you’ve been bullshitting all day in Parliament,’’ Mr Mathieson said. “So, if he mentions the Prime Minister’s partner one more time, one more time, there will be a legal action against Denis The Vet.

“You hear me? One more time against the ex-Prime Minister’s partner there will be a lawsuit against him so long — I am not, I am not, anything to do with Geoff Shaw, in any way shape or form. So, if he mentions me one more time, I am telling you right now. OK? That’s it. Bang !”

Reports of the message circulated in Canberra last week, with Liberal staffers shocked that Mr Mathieson would threaten to sue the premier.

Three years ago, Ms Gillard wrote a personal cheque for $4243 to repay the entitlements after Mr Mathieson used the Prime Minister’s taxpayer-funded car to sell shampoo and hair products.

On June 11, the same day that Mr Mathieson left the message, Mr Napthine had ­referred to the incident in Victorian Parliament. Mr Mathieson declined to comment on the matter yesterday. Speaking from the US, Ms Gillard’s spokesman Bruce Wolpe said: “My sense is he wouldn’t want to say anything about it.”

Mr Napthine’s office also declined to comment. But The Sunday Telegraph understands the mobile phone number of the caller recorded by the answer machine matches a mobile phone understood to be used by Mr Mathieson.

Shortly after Ms Gillard’s office was contacted that phone number was switched off and now has a message saying it is no longer connected.

Just weeks ago, the former hairdresser ­attacked Prime Minister Tony Abbott’s wife Margie for not doing enough charity work.
