Conservatives The Conservatives campaigned on economic issues, pledging to control inflation and to reduce the increasing power of the trade unions who supported mass strikes. They also employed the advertising agency Saatchi & Saatchi who had created the "Labour Isn't Working" poster. The Conservative campaign was focused on gaining support from traditional Labour voters who had never voted Conservative before, first-time voters, and people who had voted Liberal in 1974. Thatcher's advisers, Gordon Reece and Timothy Bell, co-ordinated their presentation with the editor of The Sun, Larry Lamb.

Thatcher's stance on immigration in the late 1970s (following the vast immigration from Asian and African-Caribbean nations during the 1950s and 1960s) was perceived
