The government is generally referred to simply as "the Provisional Government". It is sometimes referred to as "the Provisional Government of Ireland", or "the Provisional Government of the Irish Free State". In article 17 of the Treaty, under which it was set up, it was referred to merely as "a provisional Government", although Article 15, dealing with discussions between North and South, referred to "the provisional Government of Southern Ireland hereinafter constituted". The Irish Free State (Agreement) Act 1922, which implemented the Treaty in British law, referred to it only as "the Provisional Government established under that Article 17". Similarly, the Mansion House meeting at which the government was constituted resolved that "a Provisional Government be and is hereby constituted". The "Irish Times" story on the meeting referred to it as "the Irish Free State Provisional Government", while its editorial of the same date referred to it as "the Provisional Government of Ireland". A committee set up to deal with Irish affairs, headed by Winston Churchill, was called the "Provisional Government of Ireland Committee".
