I just saw the notice that Philip Lee will do a MN webchat tomorrow (and the first three questions about self ID). He's an ex Conservative MP who defected to the LibDems. There are a few who did the same:
Sarah Wollaston
Philip Lee
Sam Gyimah
Heidi Allen
Antoinette Sandbach
I don't know their views on selfID but as former Tories might they be less blinkered on the issue? If they have seats after 12 December I wondered if any of them might be especially worth targeting to discuss the issue to try and inject some sense (or at least some debate, you know) into the LibDems.
Sam Gyimah apparently has concerns about university safe-space policies, which is interesting.
