It is hardly surprising that someone open to rejoining the EU would be open to free movement. Burnham's romanticised picture of EU membership ignores the fact that we literally had no idea who was coming into the country before 2016. We were always told there were 3 million EU citizens in Britain. When we counted them we discovered there were 6 million. Any attempt to return to free movement has to reckon with the fact that a country like Spain has legalised the status of a million plus illegal migrants since then, and with the very visible tensions and anxieties amongst EU member states on the subject. There can be no viable policy which doesn't involve HMG having full control over who comes into this country. We aren't there at the moment, but we will need to get there in the end. Andy Burnham may not understand this now, but he will have to do so eventually.
