Writing in Sir Anthony Seldon’s book The Brexit Effect, Miliband urged a future Labour government to prioritise rebuilding closer ties with the EU to mitigate further economic consequences. His remarks coincide with The Independent's new campaign, "Europe: The Way Back", which will investigate the impact of Brexit and explore the UK's future relationship with Europe. Miliband highlighted research indicating that business investment is 12-18 per cent lower than it would have been without Brexit, with employment and productivity also seeing declines of 3-4 per cent. He also contended that leaving the EU has not resolved immigration challenges and emphasised the critical importance of the UK's relationship with European nations amid increasing global disorder.
