Premier Daniel Andrews is facing an internal backlash over a deal that could land former Emergency Services Minister Jane Garrett a safe seat in State Parliament's upper house.

Ms Garrett is currently the member for the marginal seat of Brunswick, but wants to run for a safer seat in either the Victorian or federal parliament.

Now, under a peace deal being negotiated among Labor’s Victorian factions, she may be offered a state upper house position.

Mr Andrews and Opposition Leader Bill Shorten are understood to have negotiated a deal for Ms Garrett to enter the Victorian Upper House at November's state election.

The party’s groupings look close to agreeing a deal to carve up the vacant federal parliamentary seats in the state, to meet demands from Ms Garrett’s allies to "find a home" for the high-profile former minister.
