Tensions in Victoria's Labor government over the assisted dying bill have spilled out in an accidental text message.
Health Minister Jill Hennessy called Deputy Premier James Merlino a "c***" in a text message sent to him by mistake on Wednesday night, it has been confirmed by numerous parliamentary sources.
Mr Merlino, a fierce opponent to the government's bid to legalise a strictly monitored euthanasia scheme, had proposed an amendment which would have killed off the bill, long championed as a flagship policy by Labor.
The amendment was narrowly defeated and it's understood Mr Merlino is angry about the text message from his colleague.
His office declined to comment on the matter.
A spokeswoman for Ms Hennessy wasn't giving anything away.
"The minister doesn't comment on private conversations," she told AAP.
