We have been working with Migration Policy Institute to deliver this element of the research. It involves interviewing institutional actors in Britain (e.g. FCO, DWP, HMRC), within the European Commission, and in seven EU Member States—Spain, France, Ireland, Germany, the Netherlands, Cyprus and Sweden—to capture how institutional actors with responsibilities for these British population understand, communicate, manage and mediate the effects of the Brexit negotiations on UK citizens living in the EU27. This element of the research keeps a finger on the pulse of the challenges Brexit presents for the formal support services regularly dealing with British overseas populations and maps and evaluates the solutions such institutional actors identify, develop and promote to overcome such challenges, including the management of potential return migration.
