Good briefing paper by the House of Commons library (as always!) on the end of free movement rights and what has been said so far. It also mentioned without comment the now patently false assurances of the Leave campaigners.

It remains to be seen how the Government may choose to offer such protection. It is not known whether it would require certain criteria to be met or whether conditions would be placed upon rights of residence. Nor is it clear by what procedures such residence rights would be sought and obtained. The Migration Observatory at Oxford emphasises the sheer scale of the administrative exercise that would be required to register all EU citizens currently resident in the UK.

British citizens living elsewhere in the EU have warned of the unintended consequences of Brexit should the Government fail to secure protection of their current status and rights in their host countries.
