Labour’s rules allowing affiliate unions to vote for its leader makes some members more equal than others.
Those who are both individual members of the party and a voting delegate of an affiliate union or a member of a union which will allow all its members a vote will get two votes.
Rob Hosking points out that a few members are even more unequal.
All MPs get two votes, one as a member of caucus and the second as a member of the party. But those who are members of affiliate union will get a third vote.
That is a perversion of democracy where all people are supposed to be equally equal.
