Former prime minister Scott Morrison has branded the robo-debt royal commission findings against him as disproportionate, wrong, unsubstantiated and absurd, while accusing Labor of abusing the commission process to carry out a “political lynching”.

In a statement to parliament on Monday, Mr Morrison also accused Labor of “rank hypocrisy”, given the ALP, when in opposition, went to both the 2016 and 2019 federal elections counting the forecast budget savings from robo-debt in its own costings promises.
