Conservatives, with a late surge in their support. Powell's supporters claim that he contributed to this surprise victory. In "exhaustive research" on the election, the American pollster Douglas Schoen and University of Oxford academic R. W. Johnson believed it "beyond dispute" that Powell had attracted 2.5 million votes to the Conservatives, but the Conservative vote had increased by only 1.7 million since 1966. However the Conservative victory was reportedly not to Powell's advantage, who according to friends "sat in his head in his hands" for many days afterwards. Powell had voted against the Schuman Declaration in 1950 and had supported entry into the European Coal and Steel Community only because he believed that it was simply a means to secure free trade. In March 1969, he opposed the UK's joining the European Economic Community. Opposition to entry had hitherto been confined largely to the Labour Party but now, he said, it was clear to him that the sovereignty of Parliament was in question, as was UK's very survival as a nation. This nationalist analysis attracted millions of middle-class Conservatives and others, and as much as anything else it made Powell the implacable enemy of Heath, a fervent pro-European; but there was already enmity between the two. During 1970, Powell gave speeches about the EEC in Lyons (in French), Frankfurt (in German), Turin (in Italian) and The Hague. The Conservatives had promised at the 1970 general election in relation to the Common Market. "Our sole commitment is to negotiate; no more, no less". When Heath signed an accession treaty before Parliament had even debated the issue, the second reading of the Bill to put the Treaty into law was passed by just eight votes on second reading, and it became clear that the British people would have no further say in the matter, Powell declared his hostility to his party's line. He voted against the government on every one of the 104 divisions in the course of the European Communities Bill. When finally he lost this struggle, after three years of campaigning on the question, he decided he could no longer sit in a parliament that he believed was no longer sovereign. A Daily Express opinion poll in 1972 showed Powell to be the most popular politician in the country. In mid-1972, he prepared to resign the Conservative whip and changed his mind only because of fears of a renewed wave
