Victorian Liberal MP Julia Banks says she won't be recontesting the next election saying last week's leadership chaos was the last straw.
Ms Banks says she agrees with hundreds of her constituents who have told her they wanted Malcolm Turnbull to remain as prime minister with Julie Bishop as deputy.
She says she's been subjected to bullying and intimidation from her own party and the ALP.
Ms Banks says she's always put Australia's national interest before internal political games, factional party grudges, self-proclaimed powerbrokers and certain media personalities who bear vindictive, mean spirited grudges.
Julia Banks won the marginal seat of Chisholm at the 2016 election.
