In line with Marxist tradition the actual CPGB-PCC contributors write under a variety of assumed names. John Chamberlain usually calls himself "Jack Conrad" or "John Bridge". This explains the multiplicity of authors but familiar sets of prose. The "Weekly Worker" has been estimated to have as few as 37 members as of 2007 (which is consistent with the £1,000 the party attempts to raise through the paper every month to cover printing costs). This is an increase on the 10 or so who were initially part of "The Leninist".
