Impact on Women's Representation
The departure of both Sussan Ley from parliament and Charlotte Mortlock from the party signifies a potential reduction in female representation within Liberal ranks. Prior to these events, the Liberal Party's House of Representatives had a small contingent of female MPs. Ley's exit specifically reduces this number. Mortlock's resignation from the party also raises questions about the future of advocacy for women within the Liberal Party.
Pre-Ley/Mortlock Departure: The number of female Liberal MPs in the House of Representatives was six (including Ley).
Post-Ley/Mortlock Departure: The number of female Liberal MPs in the House of Representatives is reported to be five.
Perspectives on Ley's Ousting and its Consequences
