Blue passports will be issued for the first time in almost three decades from next month to mark Britain’s departure from the EU, the government has announced, Eurasia Diary reports citing The Guardian.

They will replace the standard-issue burgundy passports that were rolled out across EU countries from 1988.

The home secretary, Priti Patel, welcomed the switch back to blue, but pro-European campaigners and nationalist politicians in Northern Ireland predicted the new passports would result in Britons entering the slow lane at airports and ports throughout the EU.

The Home Office says the blue passport will be “the greenest British passport ever”. A spokesperson said: “The carbon footprint produced through manufacture will be reduced to net zero, through projects such as planting trees.”

It is also promoting the passport as the most technologically advanced. The spokesperson said there was “a raft of new and updated security features, including a hard-wearing, super-strength polycarbonate data page, which contains innovative technologies embedded into the document, to keep personal data secure”.

The new-look passport incorporates the latest and most secure printing and design techniques, the spokesperson said, which would offer better protection against identity theft and fraud.

Patel said: “Leaving the European Union gave us a unique opportunity to restore our national identity and forge a new path in the world. By returning to the iconic blue and gold design, the British passport will once again be entwined with our national identity and I cannot wait to travel on one.”

The home secretary’s enthusiasm was not shared by the European Movement. Edward McMillan-Scott, the group’s patron and an MEP for 30 years, said the blue passport would be seen as offensive to many Europeans.

“It will be seen as a symbol of the attitude prevailing in the Conservative party towards the rest of Europe that is isolationist, ignorant and self-destructive,” he said.
