Note: The official Liberal candidate for Cardiff South East in 1979, Christopher Bailey, deliberately failed to submit his nomination papers in time and advised Liberal voters to vote Conservative. He was subsequently expelled from the Liberal Party.
This election was remembered for when Pat Arrowsmith heckled Callaghan throughout the election declaration. During the customary victory speech, Callaghan continued to be interrupted throughout and Callaghan remarked it was the first time he had ‘conducted a duet’ whilst giving a victory speech. When Arrowsmith refused to desist, Callaghan and the other candidates left the stage. Arrowsmith (who had been arrested in Cardiff the day before the election) made a short statement about Northern Ireland. These scenes were broadcast live on BBC Election 79.
