How Cameron can win an EU referendum

Now that Cameron has won Britain’s general election, he must fulfil his promise of negotiating reforms to the EU and then holding an in-or-out referendum before the end of 2017. Cameron has made it clear that he wants Britain to stay in a reformed EU, but it will be hard for him to achieve reforms, and very hard to win a referendum.

* One reason why British influence in Europe has dwindled is that it has often sat on the sidelines and appeared happy for others to lead

Many in his own party – and the UK’s eurosceptic media – will urge him to demand major changes to the treaties, arguing that unless he extracts major concessions from other member-states, the British people will never agree to stay in the club.

But in fact he will need to be diplomatic and constructive, for the British brand in the EU is much more toxic than many people in the UK appreciate. Here are five pieces of advice for Cameron.

First, do not over-bid. If Cameron tries to make fundamental changes to the way the EU works, he will fail. Britain’s partners have no appetite for treaty change: a new treaty would need to be ratified in all 28 member-states, some of which would have to hold referendums.

The process of changing the treaties would take many years, and most governments – including that of Germany, which leads the EU – fear that reopening the treaties would be like opening Pandora’s Box.

There is no chance of a new treaty being ratified by 28 countries before the end of 2017. The best that Cameron could obtain would be a promise of very minor treaty changes, to be ratified at some point in the future.

Second, make the case for EU membership. Cameron did so with his Bloomberg speech of January 2013 – but never followed up, because he did not want to annoy his party’s eurosceptics or potential UKIP voters.

Britain’s partners will not take Cameron seriously until they see that he is prepared to explain to the British the benefits of EU membership – and thus be ready to make enemies in his own party. Cameron surely understands that during the referendum campaign the Conservative Party will inevitably split into two hostile camps – and that may undermine its long term cohesion.

Third, take initiatives in the EU and seek to lead in areas where Britain has expertise. One reason why British influence has dwindled in recent years is that it has often sat on the sidelines and appeared happy for others to lead.

Britain’s EU partners would listen to it with more respect if it made concrete proposals in areas such as foreign and defence policy, co-operation on policing and counter-terrorism, climate and energy, or trade and the single market. Many other member-states would welcome a more pro-active Britain.

Fourth, work hard at building alliances and making friends. Cameron has very few close friends in the EU. When the European Council voted on Jean-Claude Juncker’s appointment as Commission president last June, only Hungary’s Viktor Orban joined Cameron in opposition. Angela Merkel is something of a friend, on a good day, but she and Cameron are prone to misunderstand each other (as they did over Juncker’s appointment).

Other leaders tend to complain that Cameron is a very transactional politician who does not invest sufficient time in building relationships with them. Britain’s relations with several Central European countries have frayed in recent years, largely because of the Conservatives’ anti-immigration rhetoric.

Of course, the problem is not just Cameron. Under the last Labour government, too, many of the EU’s smaller members complained that British ministers and officials seldom took them seriously, for example by making the effort to travel to discuss areas where they could work together.

Fifth and finally, clubs have not only rules but also mores. British politicians tend to forget that their rambunctious style of domestic politics – involving confrontation, rudeness and a win-or-lose psychology – goes down badly in Brussels.

The EU works through long negotiations and compromises that end in everyone feeling that they have got something. Sometimes Cameron gets this: two years ago he worked patiently with Germany and other partners to get a good deal on the EU budget, shrinking its size.

Sometimes he does not: prior to the appointment of Juncker, Cameron told some other leaders that he would campaign to take Britain out of the EU if the Luxembourger was appointed. Such threats alienate potential allies.

Cameron has to choose the date of the referendum. There is a strong case for 2016 rather than 2017. The longer it is delayed, the more the climate of uncertainty will afflict the British economy and potentially deter foreign investment. Furthermore, newly-elected governments usually have more credibility and popularity than tired governments in mid-term.

If the referendum happened at the end of 2017, some voters might vote against the EU only because they were fed up with Cameron. Then there is the electoral cycle of other key countries to consider: both Merkel and France’s President François Hollande face elections in 2017 and will be unwilling to make big concessions to the UK in the period leading up to them.

Cameron must also decide which reforms to prioritise. Cameron and his officials have given several hints of what Britain’s priorities will be:

• He will ask for limits on the in-work and out-of-work benefits available to migrants from EU countries. As my colleague Camino Mortera has written, several of his demands would be difficult to achieve and require treaty change.

• He will try to shift the institutional balance in the EU, so that the Commission becomes less dependent on the European Parliament than it has been in recent years, and closer to the Council of Ministers. Part of this rebalancing would involve giving national parliaments a bigger role in scrutinising subsidiarity and proportionality in EU rule-making.

• He will try to introduce safeguards for the single market. There is a potential risk that the 19 countries in the euro will club together, caucus and seek to impose their views on the broader 28-country single market. In fact such caucusing has not yet happened, but Cameron will ask for new mechanisms to ensure that it cannot.

• He will urge the EU to pursue British priorities on economic policy-making, such as negotiating more trade agreements, extending the single market into services and the digital economy, and improving the quality while minimising the quantity of regulation. In fact the Juncker Commission is doing most of these things already, but Cameron will need to dress this up as a triumph for his agenda.

• He also is keen to get some sort of opt out from treaty language on ‘ever-closer union’. And he will seek radical changes to Britain’s relationship with the European Convention on Human Rights (though this is separate from the EU).

None of this would be easy to negotiate, but on most of these dossiers Cameron will find allies as well as opponents. So far, Britain’s partners have not taken the question of Brexit sufficiently seriously. They have been pre-occupied with the problems of Russia and Greece.

Many EU leaders were praying for a Labour victory. They have not given much thought to the areas in which they could help Cameron to achieve some of what he wants. A successful British renegotiation will require moderation and constructive diplomacy on their part as well as that of Cameron.

Other leaders will now have to consider the impact of a British departure on the EU. Economically, the EU would lose its biggest champion of free trade and the single market.

In terms of foreign and defence policy, the British – despite recent defence cuts, and their reluctance to become involved in the diplomacy over Ukraine – have serious capabilities; without the UK, the EU would find it harder to become any kind of power. If the EU lost one of its two countries with seats on the UN Security Council, other powers would take it less seriously.

And then there is the transatlantic relationship: though UK-US ties are weaker than they were, the British have so many economic and cultural links to the Americans that they can often explain the EU to them; and they can help continental Europeans to understand the US. For example, the UK has played a key role in forging transatlantic agreements on counter-terrorism.

Finally, there is the German question. Germany’s weight in the EU often dominates economic decision-making, and is increasingly important on foreign policy, too. A Brexit would leave Germany even more preponderant, which would concern a lot of other countries – as well as a number of Germans.

Brexit is far from inevitable. Recent opinion polls in Britain suggest that more voters wish to stay in the EU than leave. But for a referendum to be won, Cameron needs to become more strategic and less tactical. And Britain’s EU partners need to help him to frame a deal that he can sell to the British people.
