Inside Europe: Ten Years of Turmoil

David Cameron's closest advisers reveal how he tried to tackle the Europe question, and his battles at home and in Brussels before the referendum.

Episode Two, Going For Broke, takes us deep inside crucial European Councils as the leaders and their Ministers try to avert financial disaster.

It is a clash between the cautious Angela Merkel and the feisty Nicolas Sarkozy over how to deal with the near-bankruptcy of Greece. The crisis spreads to threaten the euro itself.

Episode three, Unstoppable, forensically exposes how the European leaders fought each other over how to deal with the arrival of refugees and migrants from north Africa and Syria.

As hundreds of thousands marched north, Europe divided. Nowhere was this clearer than the passionate arguments between the Commission President, Jean-Claude Juncker, who wanted to give the EU power to solve the crisis, and the European Council President, Donald Tusk, who was trying to protect the interests of its member states. The Eastern bloc wanted none of Juncker's solution - Hungary's Viktor Orban took matters into his own hands and closed its borders to the migrants.
