Tonight, New Zealand time, the polls open to allow people in the UK to vote on whether or not they stay in the European Union.
The euro makes life easier for people travelling between the countries which use it. But monetary union doesn’t work properly when the parties to it don’t have economic union.
The UK was sensible to retain its own currency.However, the rush to swap pounds for euro shows people believe victory for the leave campaign would result in a substantial fall in the value of the pound.
The theory of the EU has a lot to commend it – a single market with free movement of people and trade. But politics and a bloated bureaucracy have too often meant the promise hasn’t been realised.
Whatever the people of Britain and Northern Ireland vote for or against Brexit, the EU needs major reform.
