After the Conservative Party achieved an overall majority in the 2019 general election, the group announced that it would rebrand in 2020 to push for a fair deal following the UK's exit from the EU in January 2020.

[8][9] In March 2018, HuffPost reported that several pro-EU groups had moved into an office together in London's Millbank Tower in order to co-ordinate their campaign to retain strong links between Britain and the European Union.

Umunna commented, "In our democracy, it is vital that the people get their say on Brexit, rather than their elected representatives in Parliament being reduced to some rubber stamp for whatever plan Boris Johnson, Jacob Rees-Mogg, and Michael Gove have been putting together behind closed doors".

[11] The event comprised Andy Parsons with MPs Chuka Umunna, Anna Soubry, Layla Moran, and Caroline Lucas speaking, as well as actor Patrick Stewart.

[17][18] Over the next two weeks the television presenter Gary Lineker,[19] the satirist Armando Iannucci,[20] broadcaster Gavin Esler, comedian Rory Bremner, and former Liberal Democrat leader Menzies Campbell[21] also announced their support for the campaign.

[22][23] In the same month the Press Association reported that, according to a leaked memo, People's Vote were attempting to secure a motion calling for Labour to continue to support a second referendum.

The rally was introduced by Andy Parsons and featured an interview of Jo Johnson by Gary Lineker, and speeches by MPs Anna Turley, Justine Greening, Ian Blackford, Caroline Lucas, Layla Moran, Dominic Grieve, Liz Saville Roberts and David Lammy.

[40] A Let Us Be Heard march took place on 19 October 2019,[41] coinciding with a historic Saturday sitting of Parliament to debate Prime Minister Boris Johnson's latest proposed Withdrawal Agreement.

[44][45] Rudd later resigned as chair of Open Britain but retained control of money and data through a new holding company he had formed for the purpose called Baybridge UK.

[46] Alastair Campbell, a former head of strategy and communications in Tony Blair's Downing Street, accused Rudd of putting his personal status ahead of efforts to stop Brexit through a new referendum.

In an opinion piece in The Guardian, he argued that the campaign promoted the idea that Leave voters in the 2016 referendum failed to understand what was at stake, a view that he characterised as elitist.
