European Union leaders are holding a summit where they have some unfinished business on banking union – a programme to reduce the risks of future crises. They meet a year after the crisis in Cyprus came to a head, when many bank customers had to take losses. Our Europe business correspondent Nigel Cassidy has been to Cyprus, where he spoke to the finance minister Harris Georgiades about whether the approach was right. He got an independent view from Fiona Mullen of Sapienta Economics. Meanwhile, European regulators are preparing to 'stress test' the major banks. The director of the European Banking Authority Piers Haben sets out what the exercise is intended to achieve. Financial analyst Bill Blain of Mint partners casts a sceptical eye over the tests and over the state of European banks.
