what would the uk be called if it became a republic
Republicanism in the United Kingdom In 1991, Labour MP Tony Benn introduced the Commonwealth of Britain Bill, which called for the transformation of the United Kingdom into a "democratic, federal and secular Commonwealth of Britain", with an elected President.[18] The monarchy would be abolished and replaced by a republic with a written constitution. It was read in Parliament a number of times until his retirement at the 2001 election, but never achieved a second reading.[19] Benn presented an account of his proposal in Common Sense: A New Constitution for Britain.[20]
Ireland Act 1949 This status quo remained, with Ireland participating little in the British Commonwealth and Éamon de Valera remarking in 1945 that "we are a republic" in reply to the question if he planned to declare Ireland as a republic. Then somewhat unexpectedly in 1948, during a visit to Canada, Taoiseach John A. Costello announced that Ireland was to be declared a republic. The subsequent Irish legislation, the Republic of Ireland Act 1948, provided for the abolition of the last remaining functions of the King in relation to Ireland and provided that the President of Ireland would exercise these functions in the King's place. When the Act came into force on 18 April 1949, it effectively ended Ireland's status as a British dominion. As a consequence of this, it also had the effect of ending Ireland's membership of the British Commonwealth of Nations and the existing basis upon which Ireland and its citizens were treated in the United Kingdom and other Commonwealth countries as "British subjects", not foreigners.
