Just as worrying is the arrival (back) in the party of the civil service’s favourite toytown revolutionary, Mark Serwotka, general secretary of the Public and Commercial Services Union (PCS). Having been absent from Labour’s membership rolls for 25 years (and gosh, how we missed him!), Serwotka spent the first ten minutes of his membership telling a newspaper that Labour members should get rid of their Blairite MPs and replace them with proper Labour Party representatives. By this I guess he means representatives like him, with a track record of losing elections and strikes and who only joined the party in the wake of Comrade Corbyn’s great leap forward.
