List of UK minor party and independent MPs elected
This is a list of members of the United Kingdom House of Commons who were elected as an independent or as a member of a minor political party. Excluded are the Speaker, who traditionally stands for re-election without party affiliation, and MPs who were elected from a major party but then defected during a parliamentary term. Great Britain. In Great Britain, the major parties are considered to be the Conservative and Unionist Party, the Labour Party, the Liberal Democrats and its forerunners, the Liberal Unionist Party, the various National Liberal  parties, National Labour, the Scottish National Party and Plaid Cymru. Minor party and independent MPs have been rare in recent times — there have been only 13 different persons elected as such in Great Britain since 1950. 1832–1918. Excluded during this period are MPs from the Conservative and Liberal Parties, the Labour Party but not the Labour Representation Committee, the Liberal Unionist Party, the Whigs and the Tories. Before 1885 it becomes increasingly difficult to identify which MPs were independent, and F. W. S. Craig's classification is used. Northern Ireland. MPs from the Democratic Unionist Party, Sinn Féin, Social Democratic  and Labour Party or Ulster Unionist Party, including those Ulster Unionists who stood as part of the Conservative Party, are excluded. While these four are all currently regarded as major parties, each of these parties has at times held only a single seat (or none, in the cases of Sinn Féin, the SDLP, and the UUP), and for many years Sinn Féin was a banned organisation and did not contest elections. Also excluded are MPs from the Nationalist Party, which dissolved in 1977 but was formerly considered a major party. Ireland. All MPs are listed except those from the Irish  Unionist Alliance (affiliated to the Conservative Party during this period), the Nationalist Party, Sinn Féin, the Liberal Party, the Liberal Unionist Party and the Home Rule candidates.
