There are some who are quite experienced. There's also an interesting issue with regard to age of first election, if you see what I mean. One tends to assume they'll be young, but they're not young in every case. There are women of quite a wide variety of ages entering for the first time. There was concern in 2015 because several first-term female members unexpectedly stood down and did not wish to be re-elected. I think that was from a mixture of personal circumstances, but there was also concern as to whether that suggested an unfriendly culture or a failure of our family-friendly policies in some broad perspective.
I think Professor Childs will probably be better placed to answer that.
