State Party Membership Rules
Every member of the Liberal Democrats belongs to a State Party. The three State Parties are England, Scotland, and Wales. As a member of a State Party, you must abide by their own membership rules. If you fail to do so, the State Party may take action against you which could result in sanctions up to and including expulsion from the Party.
You can download each State Party's membership rules here.
