The Economic Impact of Brexit and the Push to Rejoin the EU

Text
A former EU Brexit negotiator has suggested that the United Kingdom could explore rejoining the European Union, according to reports from Bulgarian news outlet Новини СЕГА. The comment comes amid ongoing discussions about the economic repercussions of Brexit, with some analyses indicating a 6% contraction in the UK’s GDP over the past decade.

Michel Barnier, the EU’s chief negotiator during the Brexit process, reportedly raised the possibility of the UK reconsidering its departure in a recent interview. Barnier, who led the EU’s discussions with the UK from 2016 to 2020, stated that “structural economic challenges and political instability in the UK have created conditions where rejoining the EU could be a viable option,” according to Новини СЕГА. The outlet cited an unnamed source close to Barnier, though no official statement from the EU has confirmed the remarks.

Economic Impact of Brexit
The UK’s decision to leave the EU in 2020 has been linked to significant economic strain, according to multiple analyses. A report cited by manager.bg noted that the country’s economy has lost 6% of its GDP since the Brexit referendum in 2016. The study, conducted by a London-based economic think tank, attributed the decline to reduced trade flows, regulatory divergence, and uncertainty in investment.

Similar findings were echoed in an article from DarikNews.bg, which highlighted that sectors such as manufacturing and finance have faced prolonged disruptions. The report cited data from the UK’s Office for National Statistics showing a 12% drop in cross-border trade with the EU between 2019 and 2023.

Calls for Rejoining the EU
Barnier’s remarks align with growing calls from within the UK for a reassessment of Brexit. Political analysts in the UK have pointed to rising public dissatisfaction with the economic consequences of the withdrawal, particularly in regions reliant on EU funding. A survey published in Investor.bg in May 2026 found that 47% of UK citizens now support reconsidering membership in the EU, up from 32% in 2020.

The former negotiator’s comments also coincide with a broader debate about the long-term viability of the UK’s post-Brexit trade agreements. Critics argue that the current framework has failed to replicate the benefits of EU membership, while proponents of Brexit maintain that the country has regained sovereignty.

Context and Reactions
The EU has not publicly responded to Barnier’s remarks, but officials have previously emphasized that any reconsideration of membership would require a “comprehensive review of the terms” of rejoining. A spokesperson for the European Commission stated in a written statement, “The EU remains open to dialogue with the UK, but any discussion on rejoining must address the complexities of aligning with EU laws and institutions.”

In the UK, reactions to the reports have been divided. Some politicians have dismissed the idea as unrealistic, while others have called for a formal review of the Brexit agreement. Labour Party leader Keir Starmer said in a June 2026 address, “The economic costs of Brexit are clear, and we must explore all options to stabilize the economy.”

Broader Implications
The potential for the UK to rejoin the EU raises questions about the future of European integration. Analysts note that such a move would require significant political and legal changes, including negotiations on trade, migration, and regulatory alignment.

A comparative analysis of economic data from the past decade reveals that the UK’s GDP growth has lagged behind other European nations. According to a 2025 study by the European Central Bank, the UK’s annual GDP growth averaged 1.2% from 2016 to 2025, compared to 2.1% in the Eurozone.

As the debate continues, the focus remains on the long-term consequences of Brexit for both the UK and the EU. With the next UK general election approaching, the issue is likely to dominate political discourse in the coming months.
