This page lists opinion polling for a United Ireland also known as a New Ireland.
The Good Friday Agreement states that "the Secretary of State" should call a referendum "if at any time it appears likely to him that a majority of those voting would express a wish that Northern Ireland should cease to be part of the United Kingdom and form part of a united Ireland." [1]

An opinion poll of 1,089 people conducted by LucidTalk in 2014 around the time of the Scottish referendum posed several questions. On the question of whether or not there should be a border poll, 47% said "yes", 37% "no" and 16% "don't know". [45] On the question, "If a referendum on Irish Unity was called under the Good Friday Agreement would you vote: Yes for unity as soon as possible, Yes for unity in 20 years, or No for Northern Ireland to remain as it is", the results were as follows.

A 2019 poll by Ipsos Mori and King's College London asked people in Britain (England, Scotland, and Wales): "If there were to be a referendum in Northern Ireland on its future, would you personally prefer Northern Ireland to choose to stay in the UK or leave the UK and join the Republic of Ireland?" The responses revealed that 36% wanted Northern Ireland to stay in the UK, 19% wanted it to join the Republic, 36% had no preference, and 9% were undecided. [65] It further revealed that support for Northern Ireland remaining in the UK was highest among those who intended to vote Conservative (49%) compared to 35% for Labour voters and 31% for Liberal Democrat voters. [65]
A 2023 state of the union poll asking if Ireland should unite showed that respondents from Northern Ireland, Scotland, Wales and England all had net positive views on the unification. On a scale between -10 to definitely remain in the UK to +10 to definitely unite Ireland; the people of Scotland had a net score of +1.9, England at +0.9, Wales at +0.6, and those in Northern Ireland at +0.6 also. [66]
Scottish independence is the idea of Scotland regaining its independence and once again becoming a sovereign state, independent from the United Kingdom. The term Scottish independence refers to the political movement that is campaigning to bring it about.
United Ireland, also referred to as Irish reunification or a New Ireland, is the proposition that all of the island of Ireland should be a single sovereign state. At present, the island is divided politically: the sovereign state of Ireland has jurisdiction over the majority of Ireland, while Northern Ireland, which lies entirely within the Irish province of Ulster, is part of the United Kingdom. Achieving a united Ireland is a central tenet of Irish nationalism and Republicanism, particularly of both mainstream and dissident republican political and paramilitary organisations. Unionists support Northern Ireland remaining part of the United Kingdom and oppose Irish unification.
English independence is a political stance advocating secession of England from the United Kingdom. Support for secession of England has been influenced by the increasing devolution of political powers to Scotland, Wales and Northern Ireland, where independence from the United Kingdom is a prominent subject of political debate.
In the United Kingdom, unionism is a political stance favouring the continued unity of England, Scotland, Wales and Northern Ireland as one sovereign state, the United Kingdom of Great Britain and Northern Ireland. Those who support the union are referred to as Unionists. Though not all unionists are nationalists, UK or British unionism is associated with British nationalism, which asserts that the British are a nation and promotes the cultural unity of the Britons, which may include people of English, Scottish, Welsh, Irish, Cornish, Jersey, Manx and Guernsey descent.
Relations between the European Union (EU) and the United Kingdom of Great Britain and Northern Ireland (UK) are governed, since 1 January 2021, by the EU–UK Trade and Cooperation Agreement (TCA).
On 23 June 2016, a referendum, commonly referred to as the EU referendum or the Brexit referendum, took place in the United Kingdom (UK) and Gibraltar to ask the electorate whether the country should remain a member of, or leave, the European Union (EU). The referendum resulted in 51.9% of the votes cast being in favour of leaving the EU, triggering calls to begin the process of the country's withdrawal from the EU commonly termed "Brexit".
Brexit was the withdrawal of the United Kingdom (UK) from the European Union (EU). Following a referendum on 23 June 2016, Brexit officially took place at 23:00 GMT on 31 January 2020. The UK is the only sovereign country to have left the EU. The UK had been a member state of the EU or its predecessor, the European Communities (EC), since 1 January 1973. Following Brexit, EU law and the Court of Justice of the European Union no longer have primacy over British laws. The European Union (Withdrawal) Act 2018 retains relevant EU law as domestic law, which the UK can amend or repeal.
This page lists the public opinion polls that were conducted in relation to the 2014 Scottish independence referendum, that was held on 18 September 2014. Overall, polls showed that support for a "No" vote was dominant until the end of August 2014, when support for a "Yes" vote gained momentum and the gap closed significantly, with at least one poll placing the "Yes" vote ahead. In the final week of the campaign, polls showed the "No" vote to be consistently but somewhat narrowly ahead. There were no exit polls although a YouGov post-election poll was published shortly after the polls closed. For the history of the campaign itself see 2014 Scottish independence referendum, Yes Scotland, and Better Together (campaign).
The 2019 United Kingdom general election was held on Thursday 12 December 2019 with 47,074,800 registered voters entitled to vote to elect members of the House of Commons. The Conservative Party won a landslide victory with a majority of 80 seats, a net gain of 48, on 43.6% of the popular vote, the highest percentage for any party since the 1979 general election.
The 2019 European Parliament election was the United Kingdom's component of the 2019 European Parliament election, held on Thursday 23 May 2019 and the results were announced on Sunday 26 and Monday 27 May 2019, after all the other EU countries had voted. This was the United Kingdom's final participation in a European Parliament election before leaving the European Union on 31 January 2020, and was also the last election to be held under the provisions of the European Parliamentary Elections Act 2002 before its repeal under the European Union (Withdrawal) Act 2018.
The referendum on EU membership took place on 23 June 2016. Opinion polling for the United Kingdom European Union membership referendum was ongoing in the months between the announcement of a referendum and the referendum polling day. Polls on the general principle of the UK's membership of the European Union were carried out for a number of years prior to the referendum. Opinion polls of voters in general tended to show roughly equal proportions in favour of remaining and leaving. Polls of business leaders, scientists, and lawyers showed majorities in favour of remaining. Among non-British citizens in other EU member states, polling suggested that a majority were in favour of the UK remaining in the EU in principle, but that a similarly sized majority believed that if the UK were only able to remain in the EU on renegotiated terms then it should leave.
A second referendum on the independence of Scotland from the United Kingdom (UK) has been proposed by the Scottish Government. An independence referendum was first held on 18 September 2014, with 55% voting "No" to independence. The Scottish Government stated in its white paper for independence that voting Yes was a "once in a generation opportunity to follow a different path, and choose a new and better direction for our nation". Following the "No" vote, the cross party Smith Commission proposed areas that could be devolved to the Scottish Parliament; this led to the passing of the Scotland Act 2016, formalising new devolved policy areas in time for the 2016 Scottish Parliament election campaign.
The result in favour of Brexit of the 2016 United Kingdom European Union membership referendum is one of the most significant political events for Britain during the 21st century. The debate provoked major consideration to an array of topics, argued up-to, and beyond, the referendum on 23 June 2016. The referendum was originally conceived by David Cameron as a means to defeat the anti-EU faction within his own party by having it fail, but he misjudged the level of public support for leaving, particularly amongst Labour Party voters. Factors included sovereignty, immigration, the economy and anti-establishment politics, amongst various other influences. The result of the referendum was that 51.8% of the votes were in favour of leaving the European Union. The formal withdrawal from the EU took place at 23:00 on 31 January 2020, almost three years after Theresa May triggered Article 50 of the Lisbon Treaty on 29 March 2017. This page provides an overarching analysis of the different arguments which were presented by both the Leave and Remain campaigns.
Euroscepticism is a minority view in Ireland. Opinion polls held in the country between 2017 and 2022 indicated between 70% and 90% support for continued membership of the European Union (EU), and a 2021 'Eurobarometer' report indicating that 75% of poll respondents had a "positive image of the EU".
The impact of Brexit on the Irish border and its adjacent polities involves changes in trade, customs, immigration checks, local economies, services, recognition of qualifications, medical cooperation, and other matters, now that it is the only land border between the United Kingdom and the European Union.
The Irish backstop was a proposed protocol to a draft Brexit withdrawal agreement that never came into force. It was developed by the May government and the European Commission in December 2017 and finalised in November 2018, that aimed to prevent an evident border between the Republic of Ireland and Northern Ireland after Brexit.
A referendum on the Brexit withdrawal agreement, also referred to as a "second referendum", a "rerun", a "people's vote", or a "confirmatory public vote", was proposed by a number of politicians and pressure groups as a way to break the deadlock during the 2017–19 Parliament surrounding the meaningful vote on the Brexit deal.
The Protocol on Ireland/Northern Ireland, commonly abbreviated to the Northern Ireland Protocol, is a protocol to the Brexit withdrawal agreement that sets out Northern Ireland’s post-Brexit relationship with both the EU and Great Britain. The Withdrawal Agreement, including the Protocol, came into effect on 1 January 2021. Citing the island of Ireland's "unique circumstances," the Protocol governs unique arrangements on the island between the United Kingdom and the European Union; it regulates some aspects of trade in goods between Northern Ireland and the rest of the United Kingdom.
Opinion polling for the next United Kingdom general election is being carried out continually by various organisations to gauge voting intention. Most of the polling companies listed are members of the British Polling Council (BPC) and abide by its disclosure rules. The dates for these opinion polls range from the 2019 general election on 12 December to the present day.
The Irish Sea border is an informal term for the trade border between Northern Ireland and Great Britain. It was specified by the Ireland/Northern Ireland Protocol of the Brexit withdrawal agreement, was refined by the Joint Committee in December 2020, and came into effect on 1 January 2021 following the end of the Brexit transition period. As a result of the Agreement, Northern Ireland remains aligned to the European Single Market in a limited way for goods, whilst remaining part of the United Kingdom customs territory and the UK internal market. Its effect is that the need for customs checks on the Irish border has been avoided, and a hard border has not been re-established.
Over a quarter of people in the six counties say they have changed their mind since the Brexit vote and now support a united Ireland – bringing polling for a referendum to 45 per cent staying in the UK and 42 per cent leaving it, with 13 per cent undecided.
If Brexit led to a border poll, 52% would vote for Northern Ireland to remain part of the UK and 27% for a united Ireland.
