Prime Minister Scott Morrison and his deputy Josh Frydenberg will hold crisis talks with Victorian federal MPs on Monday, after the rout of the Liberal Party in Saturday's state election raised fears that up to six federal Coalition seats in and around Melbourne could be lost.

With the state Labor government of Daniel Andrews forecast to win 55 of the state's 88 lower house seats following Saturday's landslide, moderates, shocked at the scale of the swing towards Labor in safe inner-Melbourne seats, blamed the dumping of Malcolm Turnbull for contributing to the result.
