Lewin has previously campaigned in favour of remaining in the European Union (EU).[5] He cited his reasons for setting up Remain Labour as being due to his belief that "Brexit would hit hardest those who have least."[13] He also said it was the responsibility of the Labour party to stand against a project which he said would do "most damage" to the "poorest communities."[13]
Ahead of the 2019 general election, Lewin called for a "Remain Alliance" consisting of Labour, the Liberal Democrats and the Greens to be formed in opposition to Prime Minister Boris Johnson.[17] He said that the prospect of a No-deal Brexit was "motivation enough" to form the alliance, and called on the parties to recognise that they had "more in common" instead of exaggerating their differences "for party gain".[17]
In an article Lewin wrote for LabourList in June 2022, he said that many wearily "read reports that prove beyond doubt that Brexit has set us back" and said that the impact was seen in communities; citing a 6% rise in food prices as being "directly attributed" to leaving the EU.[18] He called on Labour to make an "early manifesto pledge" to not rejoin the EU in its first term in power, saying that any proposal would "consume" a first-term Labour government and potentially "play into the hands of the Conservatives", and also stated that he thought it was "inconceivable" that all EU member states would welcome the UK back into the EU.[18] He also called on Labour to set out priority for cooperation with the EU regarding scientific research, climate change and energy security, and also to commit to a stronger trading relationship with the EU ahead of the next general election.[18]
