The Rennard story has prompted much comment on the dramatic under-representation of women in the Lib Dems. Just 12.5 per cent (seven) of the party's 56 MPs are female, compared with 31 per cent of Labour MPs (the only party to use all-women shortlists) and 16 per cent of Tories. Aware of this problem, the Lib Dems will debate proposals at their spring conference next month to introduce "job-share candidates " in order to improve female representation. But barring a significant improvement in their poll ratings, the likelihood is that the diminished parliamentary party that returns to the Commons after 2015 will be even more male-dominated.
Back in 2011, research by the Fabian Society  showed that five of the Lib Dems' seven female MPs, including Sarah Teather, Jo Swinson and Tessa Munt, hold seats among the party's 12 most vulnerable, while none hold any of the 20 safest.
In addition, the two 'safer' seats held by Lib Dem women - Cardiff Central and Hornsey & Wood Green - are vulnerable to a Labour challenge. As Sunder Katwala noted, "both were gained in 2005 from Labour, through appeals to students and voters disillusioned with Labour over Iraq and other left-of-centre issues." Ed Miliband's repositioning of Labour and the Lib Dems' support for £9,000 tuition fees and spending cuts means they will likely struggle in such left-leaning constituencies in 2015. And with even the most optimistic Lib Dem not forecasting any gains at the next election, those women who lose their seats are unlikely to be replaced. The party has been encouraging its MPs to stand for re-election in the hope that they will benefit from an incumbency factor but this strategy has the unintentional effect of perpetuating the male dominance of the parliamentary party.
Here are those Fabian stats in full.
