¹ - Tony Benn won the most votes but was disqualified by virtue of his Peerage; the Election Court declared Malcolm St.Clair duly elected. St.Clair undertook that if the law was changed to allow Benn to disclaim his hereditary peerage, he would resign and create a by-election. The law was changed by the Peerage Act 1963 and St.Clair duly resigned, allowing Benn to return to the Commons in 1963. ² - Edwin Taylor retained the seat for the Conservatives in the by-election but lost it to Labour in the 1964 General Election. ³ - a rare occasion when an incumbent government gained a seat from the opposition in a by-election. 41st Parliament (1955 - 1959)

¹ - Tom Mitchell won the most votes in the 1955 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 was then discovered that Beattie 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 gained more votes than Mitchell and duly took his seat. Subsequently Forrest took the Ulster Unionist whip and won the seat in his new party colours at the 1959 General Election. 40th Parliament (1951 - 1955)
