The 65.1% drop in the Irish Parliamentary Party vote is the largest decrease in a party's vote between successive House of Commons elections in a single constituency. Between elections, the First World War and Easter Rising had changed the political landscape, and the Representation of the People Act 1918 had greatly increased the electorate.
