Is this the final betrayal of EU citizens?

Copy of letter published in The Guardian 21/08/2019

Dear Sir,
Your correspondent Rowena Mason says in her front page article (Guardian 19th August) that Priti Patel "wants free movement to end on the dot of 31 October."
What form will this take? How will overworked border staff distinguish between resident EU citizens eligible for settled status but not yet registered and other EU citizens? Let us remember that EU citizens have until December 31st 2020 to register and so far less than a third have done so. According to the Federation of Poles, in their letter to Boris Johnson, barely 17% of resident Poles, the largest single EU national group in this country, has registered. This is simultaneously an administrative disaster for border staff and passengers, and potentially a gross betrayal of promises to Polish and other EU residents from Boris Johnson that their pre-Brexit status will be respected.
Yours faithfully
