Michelle Grattan speaks to Deep Saini about the week in Australian politics.
Malcolm Turnbull has struck back angrily at a report that he has been helping independent Kerryn Phelps, his successor in Wentworth, as chaos continues to fracture the Liberals.
Frydenberg reiterates that the Liberal party is still a "broad church" and says he isn't concerned about other MPs like Craig Kelly following Banks' suit.
The Liberals this week are shell-shocked and unnerved after the Victorian rout and both the fact and implications of Banks' desertion.
The Victorian backbencher has announced she is quitting the party to join the crossbench, launching a scathing attack on the right wing of the Liberal Party in the process.
Morrison is conflicted. It's risky for him to play down the allegations of standover tactics, let alone fail to take seriously enough the party's need for more female MPs.
New research shows that conservative voters generally fail to see how being female can impede political success, while left-of-centre voters list gender as the main obstacle to success.

In announcing she would not contest the next election, the member for the highly-marginal Chisholm has cited bullying and intimidation for provoking her decision.
