Kevin Rudd was given no warning, but even he lasted longer than Abbott.

Julia Gillard had plenty of warnings, but even she lasted longer than Abbott. Abbott ignored all the warnings, from beginning to end - the public ones, the private ones, from his friends, his colleagues, the media. His colleagues were not being disloyal. They did not feel they had betrayed him; they believed he had betrayed them. Their motives were honourable. They didn't want him to fail; they wanted the government to succeed, and they wanted the Coalition re-elected.

In The Road to Ruin, prominent political commentator, author, and columnist for The Australian Niki Savva reveals the ruinous behaviour of former prime minister Tony Abbott and his chief of staff, Peta Credlin. Based on her unrivalled access to their colleagues, and devastating first-person accounts of what went on behind the scenes, Savva paints an unforgettable, award-winning picture of a unique duo who wielded power ruthlessly but not well.

This updated edition contains a new, 9,000-word final chapter, in which Savva reveals the inner state of the Turnbull government - and the jockeying of friends and foes alike. It is, as usual, a vivid, impeccably sourced account.
