UK After Brexit: Sovereignty Secured or Economy Endangered? (Part 2 of 5)

A 5-Part Series Exploring the Real Impact of Brexit

This five-part series will critically analyze the UK’s post-Brexit reality, weighing the benefits of sovereignty against the economic and social consequences. Each part will delve into a crucial aspect of the Brexit aftermath, offering an in-depth, balanced perspective.

This article explores the reality of post-Brexit sovereignty by examining the changes in governance, regulatory control, border policies, and the UK’s standing in global trade.


Sovereignty, in the context of Brexit, was framed as the ability of the UK to make its own laws, control its borders, and determine its own trade policies without interference from Brussels. Euro sceptics argued that EU membership constrained the UK’s decision-making, particularly through regulations imposed by the European Commission and the rulings of the European Court of Justice (ECJ).

While these objectives seemed clear, the implementation has been complex, with Brexit producing mixed results regarding Britain’s newfound independence.


Moreover, Northern Ireland remains a unique challenge. Under the Northern Ireland Protocol, a compromise was struck to prevent a hard border between Northern Ireland and the Republic of Ireland. However, this arrangement has effectively left Northern Ireland within the EU’s regulatory orbit, creating internal friction and calls for renegotiation.

Thus, while the UK has formally left the EU, its sovereignty is still influenced by the need to cooperate with the bloc, raising questions about whether power has truly shifted in Britain’s favor.


Legal Independence: One of the touted benefits of Brexit was the ability to repeal and replace EU laws with UK-specific legislation. While this has begun to happen, the pace has been slower than anticipated. In many areas—such as labor rights, environmental protections, and financial regulations—the UK has retained EU-style rules, largely because businesses benefit from regulatory consistency when trading with Europe.

Border Control and Immigration: The UK’s exit from the EU ended the free movement of people, allowing Britain to introduce a new points-based immigration system. This was seen as a victory for sovereignty, enabling the government to prioritize skilled workers and set its own migration policies.

Fishing and Coastal Rights: Another area where the UK sought to reclaim control was over its fishing waters. Brexit negotiations promised to restore access to British fisheries, yet the outcome has been contentious. While the UK gained more control over quotas, disputes with the EU over access rights have led to ongoing diplomatic tensions with countries like France. Many UK fishermen have also struggled with the added bureaucracy of exporting seafood to European markets, raising doubts about the real benefits of sovereignty in this sector.


One of Brexit’s biggest promises was that the UK would be free to strike independent trade deals with nations around the world. While the EU, as a bloc, negotiates collective trade agreements, Britain argued that it could secure better terms as a sovereign state.

However, critics argue that many of these deals replicate or even weaken the terms the UK had under the EU’s trade agreements. The economic benefits of these new deals have been modest, with government assessments suggesting limited long-term GDP growth from these agreements.

Additionally, UK financial services, a key sector of the economy, have lost some market access to the EU. London, once Europe’s undisputed financial hub, has seen portions of its business shift to Frankfurt and Paris, raising concerns about the UK’s global competitiveness.


Brexit was sold as a means to restore British sovereignty, and in many ways, the UK has regained control over its laws, immigration policies, and trade negotiations. However, sovereignty alone does not guarantee success.

The reality of Brexit’s sovereignty is more nuanced than its proponents suggested. The UK has gained autonomy but has also introduced new complexities, dependencies, and economic risks. Whether this sovereignty will translate into long-term prosperity remains an open question—one that will continue to define Britain’s post-Brexit journey.


The next part of this series will delve into the economic fallout of Brexit, examining whether the UK’s departure from the EU has led to growth, decline, or stagnation in key sectors of the economy.
