This chapter focuses on the start of the legislative process, including the crucial vote on Second Reading of the European Communities (EC) Bill (1972). It examines how the strategy of the Whips’ Office shifted as a result of a more clearly partisan political process of whipped votes on both sides of the House of Commons chamber. This led to more direct forms of pressure and persuasion in managing the dissent of Conservative anti-Marketeers, especially appeals to party loyalty from whips and ministers. The pressure was intensified by the cabinet decision to shift from a free vote on the principle of entry to a three-line whip and a vote of confidence on the Second Reading of the EC Bill. A defeat in the division lobbies would have precipitated the downfall of the Heath Government, the death of the Bill, and arguably the end of the UK’s application for EC membership under a more eurosceptic Labour Government. The chapter discusses the significance of drafting ‘a tight bill’, and the arguments over whether or not European policy should be made into an issue of confidence in the Government. It also highlights how appeals to party loyalty enabled a differentiation between two types of Conservative anti-Marketeers: those willing to risk the downfall of the Government in maintaining their right to vote according to their conscience in opposing EC entry (diehards), and those who prioritised party loyalty over their misgivings over entry (loyalists). The chapter highlights the pressure on dissenters in the days before the crucial vote and provides an in-depth analysis of the 3-day debate and the final result—a narrow escape for the Conservative Government and its Europe policy.
