The 1973 Northern Ireland border poll is a referendum held in Northern Ireland on March 8, 1973, on whether Northern Ireland should remain part of the United Kingdom or join with the Republic of Ireland to form a united Ireland. It is the first time that a major referendum has been held in any region of the United Kingdom. The referendum is boycotted by nationalists and results in a conclusive victory for remaining in the UK. On a voter turnout of 58.7 percent, 98.9 percent vote to remain in the United Kingdom, meaning the outcome among registered voters is not affected by the boycott.

The Unionist parties support the “UK” option, as do the Northern Ireland Labour Party (NILP) and the Alliance Party of Northern Ireland (APNI). However, the Alliance Party is also critical of the poll. While it supports the holding of periodic plebiscites on the constitutional link with Great Britain, the party feels that to avoid the border poll becoming a “sectarian head count,” it should ask other relevant questions such as whether the people support the UK’s white paper on Northern Ireland. Nevertheless, on February 5, 1973, the party’s chairman, Jim Hendron, states that “Support for the position of Northern Ireland as an integral part of the United Kingdom is a fundamental principle of the Alliance Party, not only for economic reasons but also because we firmly believe that a peaceful solution to our present tragic problems is only possible within a United Kingdom context. Either a Sinn Féin all-Ireland republic or a Vanguard-style Ulster republic would lead to disaster for all our people.”

The Social Democratic and Labour Party (SDLP), however, calls for a boycott of the referendum, urging its members on January 23, 1973 “to ignore completely the referendum and reject this extremely irresponsible decision by the British Government.” Gerry Fitt, leader of the SDLP, says he has organised a boycott to stop an escalation in violence.

The civil authorities are prepared for violence on polling day. They put in place mobile polling stations which can be rushed into use if there is bomb damage to scheduled poll buildings. Two days before the referendum a British soldier, Guardsman Anton Brown of the 2nd Battalion, Coldstream Guards, is shot dead in Belfast as the army searches for weapons and explosives which can be used to disrupt the upcoming referendum.

Violence by both Republican and Loyalist paramilitaries still takes place on polling day. The Provisional Irish Republican Army (IRA) explode several bombs across Northern Ireland and shoot dead a British soldier guarding a polling station in the area of the Falls Road in Belfast. The Ulster Defence Association (UDA) abducts and kills a Catholic civilian from Ballymurphy. A polling station in East Belfast guarded by the Ulster Defence Regiment (UDR) is also raided by Loyalist paramilitaries who steal several self-loading rifles.

As a political response to the referendum, the Provisional Irish Republican Army also plants four car bombs in London that day, two of which detonate, causing one death and injuring over two hundred.

The vote results in an overwhelming majority of those who voted stating they wish to remain in the UK. The nationalist boycott contributes to a turnout of only 58.7% of the electorate. In addition to taking a majority of votes cast, the UK option receives the support of 57.5% of the total electorate. According to the BBC, less than 1% of the Catholic population turn out to vote.

The referendum electorate consists of 1,030,084 adults registered to vote out of a total population of approximately 1,529,993.

The Government of the United Kingdom takes no action on receipt of the referendum result, as the result is in favour of the status quo (Northern Ireland remaining part of the UK). It is followed by an Assembly election on June 28, 1973.

Brian Faulkner, who had been the sixth and last Prime Minister of Northern Ireland, claims the result leaves “no doubt in any one’s mind what the wishes of Ulster’s people are. Despite an attempted boycott by some, almost 600,000 electors voted for the maintenance of the union with Great Britain.” He also claims that the poll showed that a “quarter of the [N.I.] Catholic population who voted … voted for the maintenance of the union” and that the result is a “blow … against IRA mythology.”
