Britain's potential rejoining of the European Union is gaining new attention, with former Prime Minister Tony Blair urging current Labour leader Andy Burnham to commit to rejoining the EU within the next decade. Blair's Tony Blair Institute (TBI) has suggested that the UK should set aside Labour's current opposition to rejoining the EU's single market and customs union, instead pursuing a "structured relationship" with the EU. The institute's report argues that the EU needs reforms to become a stronger global power, capable of competing with the U.S. and China. Blair believes Britain should play a leading role in shaping this reformed Europe, emphasizing the need for internal EU changes to make it more effective. The TBI report outlines a phased return to the EU, including rejoining the €150bn SAFE defence fund, forming a new European Energy Security Partnership, and reconnecting with EU electricity markets. It also proposes transforming the European Political Community from a discussion forum into a more powerful entity. These steps are seen as ways for the UK to reengage with Europe and contribute to its strategic and economic development. Separately, the Institute for Public Policy Research (IPPR) has highlighted the economic costs of Brexit, estimating that the UK is losing £6.5bn annually in exports due to the lack of a mutual recognition agreement with the EU. This agreement would have allowed goods from the UK to be sold in the EU without additional checks or paperwork. Sectors like automobiles, electronics, and pharmaceuticals would have benefited the most from such an agreement. A recent YouGov poll commissioned by the pro-EU group Best for Britain suggests that a commitment to rejoining the EU could help Labour secure 321 parliamentary seats, just five short of a majority. This could help unite progressive voters and prevent a potential hung parliament. While Burnham has not ruled out including a commitment to rejoining the EU in Labour's next manifesto, he has been cautious about pursuing membership in the near term. Some Labour figures, including Defence Secretary Wes Streeting, have criticized Brexit as a "catastrophic mistake" and support the idea of rejoining the EU. The TBI report also suggests that the UK could use its potential re-entry into the EU as leverage to push for reforms in European markets, arguing that pro-reformers in Brussels would be motivated to work with Britain on making the EU more economically liberal. The report recommends that Burnham replace the government's current red lines with a commitment to adopt rules and initiatives that offer economic or strategic benefits to the UK. In addition to its focus on EU relations, the TBI has advocated for slowing down the UK's net zero carbon emissions goals and promoting the increased use of artificial intelligence in government. However, these positions have drawn scrutiny, particularly over the institute's funding sources, which include technology billionaire Larry Ellison and the government of Saudi Arabia.
