Labor has fired the first shot in a new campaign that targets Liberal MPs who signed a petition that helped bring down Malcolm Turnbull, urging voters to turn against those who backed last year’s leadership spill.

The Labor campaign is using direct mail to tens of thousands of households to tell voters their Liberal MP created chaos by signing the papers to hold the leadership ballot.

The first mail-out has gone to 70,000 households in the marginal seat of Boothby in Adelaide to remind residents their local member, Nicolle Flint, was one of those who put their names to the petition.

"She followed Tony Abbott… and threw the country into complete chaos,” says the flyer.

Labor will repeat the tactic against Liberals in other capital cities using the list of signatures on the petition, which was released to the media in the hours after Mr Turnbull lost the ballot and was replaced by Scott Morrison.
