“I think Brexit was a colossal mistake,” said former London student Stubb, who has a British wife and children with dual nationality. “I am too diplomatic to express exactly what I think about those who promoted Brexit during the campaign, and those who still say that Brexit is a good thing … But I do think it’s not only shooting yourself in the foot, but it’s like amputating your leg without medical reason for doing it.”
Stubb said he recognized that British Prime Minister Keir Starmer did not aim to rejoin the EU but argued that Brits and Europeans should be “pragmatic” now and show flexibility on both sides.
Negotiations have been ongoing over moves toward deepening the partnership between London and Brussels since Starmer’s Labour won power in 2024, but progress has been held back over disagreements over youth mobility programs, student fees and how much the U.K. should pay to take part in an arms investment package.
“We need a U.K. voice in Europe. We really miss you guys,” Stubb said. “I should probably express my view that it took you seven years to negotiate yourselves out of the EU, it will take you seven years to regret it, and then seven years to come back in. I hope.”
Stubb said British membership of the EU’s customs union should be possible, alongside participation in the single market. Red lines during years of Brexit negotiations meant the U.K. left both structures five years ago, under a bare bones deal that Boris Johnson negotiated.
“We need to be super pragmatic,” he said, instead of Europeans thinking they should “continue to punish” the U.K. for leaving the bloc. “Get out of the mindset that the U.K. should not be a part of the customs union, or the U.K. should not be a part of the internal market. Think about a flexible way of dealing with it.”
More broadly, Stubb suggested the EU should reform its structures to allow more flexibility in the way member countries work together, and work with states that are not formal members of the EU.
He said Iceland is renewing its interest in becoming a member, he’d like to see Norway join the bloc, and he joked to Canadian Prime Minister Mark Carney that Canada should also take a look at EU membership when the pair went running together on Tuesday morning in London.
