In the Icelandic capital of Reykjavik, high-street pavements are lined not with cars but unaccompanied babies sleeping peacefully in their prams.

While parents nip into cafes to grab a coffee and a catch-up, or into a clothes store to try on a few items, their children are left outside.

In the country where crime rates are unbelievably low and the air quality impressively high, it would be unusual for a parent not to leave their baby outside while they ran their errands.

On June 29, the Global Peace Index, a ranking table produced by the Institute for Economics and Peace, found that Iceland, yet again, is the safest place to live in the world.
