 McGhee supported the Irish nationalist leader John Redmond and endorsed his decision in 1914 to support the British and Allied war effort at the outbreak of World War I and his condemnation of the Easter rising of 1916.But the reaction of the British government to the rising and the suspension of the Home Rule Act 1914 which Redmond had negotiated and which would have granted a strong measure of Home Rule, destroyed Redmond and his movement to achieve Home Rule through constitutional Parliamentary means.McGhee did not seek re-election in 1918.
