BRITAIN’S NEW BLUE PASSPORT
Former Prime Minister Theresa May confirmed the return of the blue passports and that they are an expression of “independence and sovereignty.”

As a member of the EU, British passports had been burgundy. New passports issued to British citizens are now blue. Travellers will also notice that the words ‘European Union’ have been removed from the cover.

Post-Brexit rules mean British passports must be valid for at least 3 months after the date they will leave the European country they are visiting.

Once the Entry/Exit System (EES) becomes operational, travellers will no longer need to have their British passport stamped.

EES will register the entry and exit of third-country nationals crossing external EU borders. Like ETIAS, EES will improve border management.

So ( Mazzer ) once this system is active, the info for entry/leaving will be recorded wether a passport is stamped or not.

Fair enough but at present it is very much an ad hoc system depending on where you enter the EU and from where quite often entering in through Cherbourg from Ireland will not result in a stamp
