The LabourCabinet of the Prime Minister, Harold Wilson, was divided over the issue.[1] The proposals had been drafted in secret by Wilson and Castle.[2] Divisions quickly appeared within the Cabinet when the proposals were presented, with the opposition led by Home Secretary James Callaghan.[2] A settlement was eventually reached with the Trades Union Congress whereby the proposals were dropped.[1]
