Labor parliamentary secretary Rebecca White, who is also the Tasmanian Labor Party president, yesterday joined caucus colleague Brenton Best and some party powerbrokers supporting a permanent split from the Greens.

``It would not be sustainable for this Labor Party to continue to operate with the Greens,'' Ms White said..

``I hear the concerns of the community and I'm happy to stand up and represent them.''

Tasmanian Young Labor president Adam Clarke echoed Ms White's anti-Greens statements, describing Greens Nick McKim and Cassy O'Connor as ``appalling ministers''.

``The Greens should be removed from cabinet immediately,'' Mr Clarke said.

It's understood a decision was taken at a Labor strategy meeting last Tuesday to sever ties with the Greens by sacking the two Greens ministers, but Ms Giddings has refused to comment on the matter for a week.

She is not expected to end her silence until Thursday when she will also name the election date in March.

Greens leader Nick McKim yesterday called on the Premier to announce the date that Tasmanians would go to the polls in a bid to shift the debate back to policy matters.

However, Mr McKim refused to comment on his own future in cabinet or say if he had spoken to the Premier in recent days.

Mr McKim also did not respond to criticism from Ms White, who said she had disagreed with his handling of some issues in his ministerial portfolios such as a prison workers' industrial dispute.

``I have fundamentally different views from some of my Greens colleagues,'' she said.

 ``I have to say that some of the issues that have caused me to make this decision have been things like scab labour in the corrections system.''

Ms White also slammed Mr McKim and Ms O'Connor for walking out of cabinet on decisions relating to important developments.

``The Greens ministers have made decisions in their ministerial roles which have reflected their ideologies, which are fundamentally different from Labor ideology and that's what I don't agree with,'' Ms White said.
