It is not much comfort to those holidaymakers who are cancelling trips because they haven't received their passports in time - but the UK travel document is one of the most powerful in the world.
British passport holders can enter more countries in the world than America, Canada, Australia and Germany.
In fact, UK passport holders have the best access to foreign countries in the world, along with Finland and Sweden.
The two Nordic countries and Great Britain can visit 173 countries using their passports, enjoying visa-free access or simply getting a visa on arrival.
In comparison, US citizens and Germans can visit 172 and Canadians can only visit 170 and Australians 168.
