Amongst the blizzard of details and arguments over our forthcoming Brexit negotiations, there is one item which stands out above all the others because it is simple and it is human and it speaks to the higher motives of human nature. I refer to the status of Europeans who live in the UK and Brits who live in Europe. The former outnumber the latter by a huge amount but even so we are talking of ordinary people and their ordinary lives which could, if either side turns vindictive, be utterly ruined.
To be fair to Mrs. May, she has already indicated that this being a matter of human concern there is no need to tie the result to the outcome of negotiations on trade and economic matters. She has stated quite clearly that if the Europeans guarantee the existing status of Brits in Europe then she will instantly reciprocate in respect of Europeans living here. The fact that this offer has not yet been taken up by the European leadership bodes ill but I suppose, in fairness, it perhaps takes them longer to agree on anything than us.
Anyway, it is a litmus test and the result will indicate to us the true nature of European politics.
