LONDON (AFX) - Bundesbank president Ernst Welteke called on the UK to join the euro, arguing it has much to gain. Speaking on BBC Radio Four, Welteke said: "The advantages of joining are more on the side of the UK than on the side of the euro zone." He suggested the British public will look more favourably on euro entry after their summer holidays, during which people will experience firsthand the convenience of the single currency. He said the European Central Bank's monetary policy has gained credibility. Welteke's comments follow yesterday's call by European Commission president Romano Prodi for the UK to join the euro.
