This committee included many prominent members of the SLP: Tom Bell, Arthur McManus, J. T. Murphy and William Paul, all of them proponents of a united communist party.
This event was not well attended, but the Committee had now moved in opposition to the SLP and directed the conference to constitute itself as the Communist Unity Group.
The CUG adopted a policy of negotiated unity with parliamentary agitation but opposition to the Labour Party.
A small number of SLP branches joined the CUG, but the group drew fewer members than they had hoped.
Although the convention approved Labour Party affiliation by 100 votes to 85, the CUG joined the CPGB, initially becoming its second largest component.
