The UK government has stated, in parliament, that it will guarantee the rights of EU nationals currently resident in the UK, providing that other EU governments reciprocate. Could not be clearer?
It would seem a simple matter for the French government to confirm that they will adopt the same approach?
There is a view in the UK, from remain followers, that we should take the moral high ground (?) by conceding our negotiating position in advance of the negotiation.
As someone who voted "remain", I understand the frustration of losing the vote, but it doesn't require us to abandon our commonsense?
