Former Prime Minister Malcolm Turnbull has made his feelings about current Prime Minister crystal clear in his new memoir A Bigger Picture. Turnbull doesn’t believe that the Morrison-led coalition deserved to win in the miracle 2019 election and criticised Morrison’s bid to portray himself as a “daggy dad” from the suburbs.

"He's a professional politician who understands marketing and messaging better than most," Mr Turnbull writes in his memoir, A Bigger Picture, The Australian reports.

"His cringe-worthy 'daggy dad' persona is more exaggerated than it is conflated, but in net terms it probably helped.

""All that aside, however, the truth is that Labor lost the election that the coalition, after the August coup, did not deserve to win."

Turnbull also took aim at his former cabinet colleagues in their roles in the coup that led to his resignation in August 2018.

Turnbull accuses Morrison of double dealing in his bid to succeed Turnbull when he had to be “propped up” as treasurer.

Turnbull also says that Peter Dutton, a coup leader, was a “narcissist” and “self-delusional” for thinking that he could be prime minister.

The memoir will be launched next Monday.
