Unite to Remain

Constituencies covered by the pact, colour-coded by standing party

Unite to Remain is a campaign and electoral pact during the 2019 United Kingdom general election. It involves three parties that support remaining in the European Union: the Liberal Democrats, the Green Party of England and Wales, and, in Wales, Plaid Cymru. Its stated goal is to avoid the spoiler effect and maximise the number of MPs elected who will oppose Brexit.

In 49 constituencies in England and 11 in Wales, only one of these parties will stand a candidate. Of the 60 constituencies, 43 will have Liberal Democrat candidates only, 10 will have Green Party candidates, and 7 will have Plaid Cymru candidates.[1][2][3][4][5] The seats covered by the pact include some defended by a Unite to Remain party, as well as target seats currently held by the Conservative or Labour parties.


Though there was no formal pact, the August 2019 Brecon and Radnorshire by-election saw the Greens and Plaid Cymru stand aside for the Liberal Democrat candidate Jane Dodds,[6] who defeated the Conservative candidate by a small margin.[7] This arrangement was mooted as being the basis for a wider-ranging "Remain Alliance".[8]

The Unite to Remain group which brokered the pact was formed by the outgoing MP for South Cambridgeshire Heidi Allen in July 2019.[9][10] The alliance approached the Labour party at an early stage, but were rebuffed.[11] The Labour peer Jim Knight is one of the directors of Unite to Remain.[12] The group was registered as a "non-party campaigner" with the Electoral Commission in November 2019.[13]

Seats were selected based on a targeted pooling of resources and only with the consent of local parties. All the parties also support electoral reform.[11] Liberal Democrat activists in constituencies where their party are standing aside were encouraged to either campaign for the Unite to Remain candidate there, or to campaign in a nearby seat.[14]

On 13 November 2019, Unite to Remain and the Renew Party announced that Renew would not contest any of the 60 Unite to Remain target seats.[15]

List of constituencies

Incumbents marked in italics are not personally standing for re-election in that constituency.

Darker rows indicate constituencies where the Unite to Remain Party won the last election (the 2017 general election or the 2019 Brecon and Radnorshire by-election). The pact also covers three seats where, during the 2017–2019 Parliament, incumbent MPs defected from other parties to the Liberal Democrats.

Psephologist John Curtice stated that the pact could be critical in "half a dozen" seats that could have otherwise been won by the Conservatives.[24]

An analysis published in the Financial Times attempted to evaluate the potential impact of the pact. This analysis applied uniform regional swing based on polling (as of early November) to the 2017 result to estimate the parties' standings in the seats before the pact, then assumed that voters for parties standing aside would transfer their support as per the pact. The analysis found that in 18 seats the Unite to Remain party would not need the pact in order to win, in 39 the pact would be insufficient to secure victory, and in two (Brecon and Radnorshire and Winchester) the pact would make the critical difference between winning and losing for the Unite to Remain party.[25]

Other pro-Remain arrangements

In addition to the Unite to Remain pact, the Liberal Democrats will not stand candidates against the following anti-Brexit or soft Brexit supporting incumbents:

  • Dominic Grieve (independent), Beaconsfield[26]
  • Gavin Shuker (independent), Luton South[27]
  • Anna Soubry (The Independent Group for Change), Broxtowe[28]

In Canterbury, the original Liberal Democrat candidate (Tim Walker) stood down in aid of the Labour incumbent Rosie Duffield, but the Lib Dems are standing a replacement candidate.[29]

In Northern Ireland, Sinn Féin, the SDLP and the Green Party in Northern Ireland have stated they will stand aside in certain constituencies to increase the chances of anti-Brexit candidates.[30]
