Two attempts were made by the Asquith coalition ministry and the Lloyd George ministry to implement the Government of Ireland Act 1914 during the war, first in May 1916, which failed to reach agreement with Unionist Ulster, then again in 1917 with the calling of the Irish Convention chaired by Horace Plunkett. It consisted of Nationalist and Unionist representatives who, by April 1918, only succeeded in agreeing a report with an 'understanding' on recommendations for the establishment of self-government. Starting in September 1919, with the Government, now led by David Lloyd George, committed under all circumstances to implementing Home Rule, the British cabinet's Committee for Ireland, under the chairmanship of former Ulster Unionist Party leader Walter Long, pushed for a radical new idea. Long proposed the creation of two Irish home rule entities, Northern Ireland and Southern Ireland, each with unicameral parliaments. An amendment to the bill in the House of Lords submitted by Lord Oranmore and Browne added a Senate for Southern Ireland, intended to bolster representation of the southern Unionist and Protestant minorities. The government opposed this on the grounds that it would weaken the function of the inter-parliament Council of Ireland, but it was passed, as was an amendment adding a Senate of Northern Ireland.
