The nationalist interest was represented by Sinn Féin who gained the two seats previously held by the Nationalist Party. Patricia McLaughlin was the first woman elected as an MP for a Northern Ireland constituency.

  1. ^ a b Tom Mitchell won the most votes at the general election but was disqualified by the House of Commons on the grounds that he was a convicted felon. A by-election was called at which Mitchell again stood and won the most votes. On this occasion an election petition was lodged and Mitchell was again disqualified with the Election Court declaring his opponent Charles Beattie duly elected. It then emerged that Beattie himself was ineligible to sit because he held offices of profit under the Crown. Beattie was indemnified by Parliament against the consequences of sitting and voting while ineligible, and a further writ was moved. In the subsequent by-election, Independent Unionist George Forrest was elected. Forrest later joined the Ulster Unionists and won the seat for the party at the 1959 general election.
