Former Foreign Secretary David Miliband has criticised Brexit's impact on Britain, characterising the country as economically and politically weakened since departing the EU's Customs Union and Single Market. He has described the consequences as a "daily anguish" he and others foresaw, framing Brexit as a process that has left the nation diminished on the international stage.

Miliband has called for Britain to establish a new, formal relationship with the European Union as a remedy for the damage he believes has been done. He has also expressed confidence that Labour's Andy Burnham would pursue closer ties with the EU, suggesting momentum exists within political circles to rebuild ties with Britain's nearest neighbours.
