Lots of people get their passport revoked, because it comes to light that the information in the application was wrong and perhaps fraudulent. That doesn't mean they become stateless, it just means they need to reapply with the correct information and perhaps face any charges if Fraud can be proved. I suspect this will happen to this chap
the issue is the toxic attitude of the the home office.
Which I hear deliberately revokes passports so they cant re enter the UK.
