Original: Although for the rest of his career Heseltine 's role in Thatcher 's downfall earned him enmity from Thatcher 's supporters in the Conservative Party this opprobrium was not universal . In a reference to the reluctance of the Cabinet to support Thatcher on the second ballot Edward Leigh said of Heseltine : '' At least he stabbed her in the front '' .
Simplified: In November 1990 , Heseltine challenged Thatcher for Conservative Party leadership and this led to Thatcher resigning , but Heseltine did not get to become party leader .
