Malone came to the attention of Special Branch, whose role it was to combat "Bolshevik subversion". He was frequently mentioned in reports to the cabinet on "Revolutionary Organisations in the United Kingdom". Malone worked to promote the affiliation of the CPGB to the Labour Party, which was under consideration as a tactical matter, urged by Lenin. Malone was particularly keen and stated "There are still a few differences between the Communist Party and the Labour Party. I am glad to realise, however, that this will soon be settled by affiliation".
