Most of the worlds 'powerful' passports are issued for 10-years, according to new research by movehub.com, a website for people moving abroad.
10-year passport issuing United Kingdom holds the top spot, with visa-free access to 173 countries.
19 nations down the list in fifth place we see that 5-year New Zealand passports allow visa free access to 168 nations.
The vast majority of the passports issued to the top 20 nations appearing on this list are issued for 10 years.
This proves that a passports validity period has little bearing on the number of countries it enables the holder to enter, rather it is more to do with the diplomatic relationships a country has with other nations.
