Commonwealth of Nations
In addition, some members treat resident citizens of other Commonwealth countries preferentially to citizens of non-Commonwealth countries. Britain and several others, mostly in the Caribbean, grant the right to vote to Commonwealth citizens who reside in those countries. In non-Commonwealth countries in which their own country is not represented, Commonwealth citizens may seek consular assistance at the British embassy. Other alternatives can also occur such as an emergency consular services agreement between Canada and Australia that began in 1986.
