The Heath government continued to experience difficulties with oil embargoes and union demands for wage increases in 1973, subsequently losing the February 1974 general election. Labour formed a minority government and went on to win a narrow majority in the October 1974 general election. Heath's leadership of the Conservative Party looked increasingly in doubt. Thatcher was not initially seen as the obvious replacement, but she eventually became the main challenger, promising a fresh start. Her main support came from the parliamentary 1922 Committee and "The Spectator", but Thatcher's time in office gave her the reputation of a pragmatist rather than that of an ideologue. She defeated Heath on the first ballot and he resigned the leadership. In the second ballot she defeated Whitelaw, Heath's preferred successor. Thatcher's election had a polarising effect on the party; her support was stronger among MPs on the right, and also among those from southern England, and those who had not attended public schools or Oxbridge.
