Prof Christian Dustmann on BBC 2: 'Billion dollar deals and how they changed your world'

"I was quite prepared... to use the cover of the statistician's analysis": Former Home Secretary David Blunkett and Prof Christian Dustmann on the 2003 report on EU accession.

In this BBC 2 programme Prof Dustmann explains how once Germany opted to temporarily restrict its boarder to migrants the "scenario we had modelled [in the report] was of course not the scenario any more".
