to what extent did the political landscape change 1918-79? ARGUMENT- changes massively, war most prominent change PARA 1- rise of labour+decline of the liberals. Lloyd-george outed asquith, seen as traitor. caused a split in the liberals, failed to reunite for 1918 election. Tories rejected coalition, allowed labour to rise. ww1 led to more trade union members, no more fptp. labour became the main opposition in 1929, parties shared the goal of getting rid of liberals PARA 2- ww2. the war ...
