Armagh. In 1983 most of it became part of the Newry and Armagh constituency, with part going to Upper Bann. From its inception Armagh had a unionist majority, though by the 1970s the nationalist vote was in the mid 30s%. In 1951, it was one of the last four seats to be uncontested in a UK general election, and in 1954 it saw the last uncontested by-election in the UK. In 1974 the Ulster Unionist Party repudiated the Sunningdale Agreement and so did not reselect the pro Sunningdale MP, John Maginnis. Instead they ran Harold McCusker, who held the seat until 1983. He was then elected for Upper Bann, which contained part of Armagh. For the history of the area post 1983, please see Newry and Armagh and Upper Bann. Elections In two-member elections the bloc voting system was used. Voters could cast a vote for one or two candidates, as they chose. The two candidates with the largest number of votes were elected. In by-elections, to fill a single seat, the first past the post system applied. There was no election in 1801. The representatives of the county in the former Parliament of Ireland became members of the 1st Parliament of the United Kingdom. After 1832, when registration of voters was introduced, a turnout figure is given for contested elections. In two-member elections, when the exact number of participating voters is unknown, this is calculated by dividing the number of votes by two. To the extent that voters did not use both their votes this will be an underestimate of turnout. If the electorate figure is unknown the last known electorate figure is used to provide an estimate of turnout. Where a party had more than one candidate in one or both of a pair of successive elections change is calculated for each individual candidate, otherwise change is based on the party vote.
