One of these is how much the public trusts its politicians.
The WEF used its executive opinion survey to ask "in your country, how do you rate the ethical standards of politicians?"
A score of 1 equates to "extremely low" while a rating of 7 is "extremely high."
The measure is therefore based on the perceptions of the population. Absolutely no country scored a 7, although Singapore topped the rankings with 6.2.
Britain did pretty well with 4.5 , and the United States came at 48th with 3.4.
However, Spain, where the prime minister Mariano Rajoy is still being accused by the opposition Socialist leader Pedro Sánchez of lying and being unfit for office due to corruption, ranks pretty badly within the index.
We looked only at the 34 OECD (Organisation for Economic Co-operation and Development) countries, which are all considered relatively developed economies with democratic systems.
