Shore was only briefly a follower of Hugh Gaitskell; his adherence to the Campaign for Nuclear Disarmament from 1958 led to a breach in relations for several years.

[5] After only a short spell on the backbenches, Wilson chose Shore to be Parliamentary Private Secretary, responsible for liaising between the Prime Minister and Labour MPs, though Denis Healey termed him "Harold's lapdog".

The Treasury had never approved of the creation of the Department for Economic Affairs and began reasserting its influence, depriving it of any significant power.

In opposition, Shore was appointed as spokesman on Europe, taking the lead in opposing Edward Heath's application to join the European Economic Community.

Shore participated in the discussions without believing that any new terms would be acceptable, and during the referendum, he joined with other anti-EEC politicians in opposing membership.

His inclination to support an autarkic economy ruled him out of consideration as a new Chancellor of the Exchequer, but Shore was moved to Secretary of State for the Environment by new Prime Minister James Callaghan in 1976.

In his 1966 book Entitled to Know, he was critical of the Nassau Agreement with the United States under which Britain's nuclear submarines were, except in a national emergency, permanently assigned to NATO.

Regarding dependence on NATO as limiting Britain's freedom of action, Shore negatively compared Britain's nuclear strategy to that of France: For if such a policy is like General de Gaulle's, based upon a deliberate and far-reaching politico-military strategy of national independence, past disengagement from NATO and détente in Europe, it merits the most careful examination.
