The eurosceptic illusion

Britain's Eurosceptics need to come clean. The media and political class have a right to be sceptical about the EU, even hostile to it. But they also have an obligation to be honest about the economic implications of a retreat from full membership of the union.

Their failure to do so is dishonest and poses a serious risk to Britain's prosperity. A newly "emancipated" Britain would not remain part of the EU's single market, at least not on the terms the Eurosceptics claim. In fact, a retreat would achieve nothing but impotence. It would not reduce the regulatory and compliance costs facing UK business and it would end our ability to shape the EU's single market.

Those calling for a renegotiation of the EU's Lisbon treaty, or of the UK's relationship with the EU more generally, ignore that this would inevitably lead to at best semi-detached membership of the EU, and more probably divorce. Eurosceptics appear to believe that a Britain outside the EU would remain part of the single market, but that it would be freed from the need to abide by EU regulation. In short, Britain could enjoy all the benefits of access to the single market but none of the costs.

This is incoherent. To remain a full member of the single market, British firms would have to abide by all its rules and regulations. A Britain that opted to withdraw from the EU would have no say over the drawing up of those rules and regulations. British interests would not be represented in Brussels and Britain would not be able to stymie regulatory drives that threaten UK prosperity. In short, British business would experience the worst of all worlds.

British manufacturers might not suffer too badly. Britain would have no say over EU product standards, which British firms would nevertheless have to comply with to sell their products in the EU. Nor would the costs of producing for the UK market fall – it would make no sense for British firms to make one set of products for the British market and another for the rest of Europe. But merchandise markets are at least already open. The real threat for the UK lies elsewhere.

Britain is by far the biggest exporter of commercial services in the EU. As such, it has a very strong interest in opening markets for those services. But a Britain that has no say over the future of the single market will not be able to use its influence to push for service sector liberalisation. It will not be able to challenge the self-serving idea put forward by other member states that a single market in merchandise goods is one thing, but open markets in services are somehow beyond the pale. Nor will it be able to ensure that regulation of service industries is not inimical to the interests of British business. This would be a major own goal.

One only has to look at the financial services industry to see the risks. If British-based providers of financial services wanted to do business in the single market, they would have to abide by whatever regulations the rest of the EU dreamed up. These would certainly be more restrictive in the absence of British involvement. At a time when other EU governments see an opportunity to cut London down to size, would it really make sense to be a bystander? How would Britain thwart the rather heavy-handed attack on the private equity and hedge fund industries operating in the EU if it had no seat at the table?

Britain needs to step up its involvement in the EU, not leave the playing field in a huff. It needs to strive to ensure that EU financial regulation is – as far as possible – proportionate and reconcilable with the UK approach. More generally, it needs to make common cause with other economically liberal member states to ensure that the EU evolves in a direction that serves British interests.

Britain's conversation about its relationship with the EU is devoid of the pragmatism and empiricism with which it is traditionally associated. Some British Eurosceptics genuinely believe that the UK can have its cake and eat it. That it could reduce the cost of EU membership while retaining all the existing and potential benefits. Others know exactly what they are doing. Their ultimate objective is for Britain to withdraw from the EU. This is a perfectly defensible aim, but those for whom this is the objective need to explain how it would be in the UK's strategic and commercial interests.
