Northern Ireland Protocol Bill

The dual regulatory regime raises more questions than it answers. If I understand the Government’s position correctly, a firm can decide to operate under one regime or the other. Say, for the sake of argument, that UK regulation banned a particular ingredient for a food product, but it was not banned by the EU. Is it my hon. Friend’s understanding of the Government’s proposals that it would be legal for a firm in Northern Ireland to sell that product with the banned ingredient in the rest of the UK, so long as the company claimed it was operating under EU rules?
