The UK has signalled it is quite willing to strip UK citizenship from people it doesn't like and then ship them goodness knows where. Being born in the UK and having UK citizenship isn't enough anymore.
It's also demonstrated a willingness to overrule reality with parliamentary proclamations.
Putting those two facts together, anyone who has the remotest chance of being a citizen of another country would be well advised to claim asylum in advance of finding themselves being (possibly literally) parachuted into a "safe" country.
