In October 1926 Shliapnikov had to accept the view of the Party Control Commission that 'neglecting to distance themselves from the United Opposition was sufficient evidence of a [Workers' Opposition] bloc [with the United Opposition]' (p. 657). The Workers' Opposition, under the leadership of Alexander Shliapnikov, were concerned at the concessions made to the peasantry under NEP and the pressure this put on industrial workers.
