Victoria's balance-of-power independent Geoff Shaw has resigned from the Liberal Party, days before it was due to meet to finalise his expulsion.

The Frankston MP quit the parliamentary wing of the Liberal Party when he became an independent a year ago, but has remained a rank-and-file member.

The party was due to hold a state assembly meeting this Friday to formalise his expulsion.

State director Damian Mantach says the meeting will no longer go ahead.

Mr Shaw has indicated he is likely to contest the seat of Frankston at the November election as an independent.

After last year's electoral redistribution, Frankston is notionally a Liberal-held seat, with a slim margin of just 0.4 per cent.

Earlier, four new Victorian Government ministers were sworn in in a ceremony at Government House.

Russell Northe, Nick Wakeling, Damian Drum and Tim Bull were elevated to Cabinet last week to replace four retiring senior ministers.

The Governor conducted the swearing-in ceremony, which was attended by the Premier and the rest of Cabinet.
