You may have a lot of questions on your mind about the group migration. Why are people coming now in such large numbers? How many more are likely to come in next 5 years? What will stop people coming? How does 2015 compare with previous movements of migrants? What do we know about how many are refugees and how many are economic migrants? How do the authorities check that migrants really are from where they say they are from? How many migrants can Europe absorb? What are other parts of the world doing?

We put these to a panel of experts: Elizabeth Collett is Director of the Migration Policy Institute Europe, Lord Green who Chairs Migration Watch, Madeleine Sumption is the Director of the Migration Observatory at the University of Oxford and Sir Paul Collier, Professor of Economics and Public Policy at the Blavatnik School of Government.
