It implies nothing BBG- it specifically states that Labour 1950 would not join a common market because the CM was not Socialist enough.
By 1994 the CM (by now the EU) was an advocate of social and welfare policies that were in alignment with Labour Party policies and values and so Labour would have no objection in joining it.
Aye I read the paper and found it interesting how the left slowly recognised the advantages of being in the club:-
"At the General and Municipal Workers’ Union (GMWU) Conference, A.M. Donnet declared:
“Joining the EEC will commit Britain to implementing the principle of equal pay. It
could also give added impetus towards longer holidays and shorter hours, and may
lead to an improvement of training methods and facilities. The harmonization of
social policies could lead to an improvement in family allowances”."
"Another new policy introduced in 1965, in line with existing Labour policies,
was the formation of a committee designed to distribute the money of the European
Development Fund to projects originating in the less-developed EEC Associated
Countries. Funds were provided for infrastructure, as well as public institutions,
such as schools and hospitals."
But I've no idea what SAB's point is. What is "left wing by backside?"
