Just how powerful is your passport?
Passport Index has listed every single passport in the world and ranked them according to how powerful each passport is - so, essentially, how many countries you can visit visa-free.
The top three countries aren't too surprising - the US, the UK and South Korea take the top spots. The US and the UK's passport holders can enter 147 countries visa-free, and South Korean citizens can enter 145. German, France, Italy and Sweden don't do too badly either, with each passport allowing its owner to visit 145 countries each.
But what about the other end of the scale? Well, if you've got a South Sudanese passport, you've picked the short straw, as you can only get into 28 countries without a visa. Other passports which rank fairly lowly on the scale are those from Myanmar (Burma), the Solomon Islands, the Palestinian Territories and Sao Tome and Principe.
