Under the Government of Ireland Act 1920 new Parliamentary constituency boundaries were enacted. Each new constituency was intended to function as a multi member seat for a devolved Parliament (elected in 1921) and (in most cases) as a single member district to return a member to the United Kingdom Parliament. The latter provision was due to take effect upon the dissolution of the Parliament elected in 1918. However, before that dissolution took place it was agreed that the Irish Free State would become a dominion outside the United Kingdom.
