Liberal 21 is a group of Liberal Party members who are not affiliated to a local party organisation.  The aim of the group is to provide the type of support and discussion that liberal members would have in a local party association but using 21st Century digital communications to allow us to communicate and interact.  Hence the name.
Thanks for the group. No branch where I live, but hoping to start one.
Interesting to hear of Liberal 21 and what it is, especially as I don' think I live within the area of a local association. Just to point out though that there is a Jewish group calling itself Liberal 21. Doesn't the Party already have a bit of a problem with name sharing?

Actually you don't. The concept of Liberal 21 - partially because the name was already in use - got subsumed into the Sheffield Liberal Page on Facebook which has now become the Progressive Liberal Page. You can find them at
How do you join Liberal 21?
