UN member states that were never a member of the Security Council
There are more than 60 member states that have never been elected to the United Nations Security Council ever since the start of the organisation in 1946.
It is arranged in alphabetical order, according to the list on the United Nations website. However, some countries like Moldova are not placed under 'M' , for example, since the first word of their full name used in the list provided by UN does not start with that letter.
