Sorry to reply twice; I can't edit my previous comment any more. It looks like there's been another poll today that is consistent with what I've seen reported previously: about 1/3 of Lib Dem voters at the last election voted Leave in the referendum, and currently Lib Dem loyalty is lowest among the major parties, with a similar proportion of Lib Dem voters at the last election expecting to vote for someone else at the next one.
