“All styles of passport will be equally valid for travel,” said the government.
The Passport Office explained: “If you renew your passport during this initial period, you may be issued with either a blue or a burgundy British passport.
“You will not be able to choose whether you get a burgundy or a blue passport.”
Travellers are advised to hold onto their expired passports, in a bid to avoid identity theft.
You can apply for a new passport if yours is lost, stolen or damaged, or is out of date.
