I'm not keen on politics in our hobby (usually goes wrong at some point IMO), I don't see any need for one or any need to object either, personally I have an NI number, a driving license, a passport, an employee number, an army number, bank accounts, credit cards, several online numbers, phone numbers, email addresses, google details, a council tax number, a car registration, a birth certificate, a marriage certificate, a marriage disolution, a college student number, a pension number(3), many more & a UKARA.
I believe it's been tried many times & it's already illegal to employ anyone without a right to work in the UK.
