Ioannis Charalambopoulos, Greek colonel and politician, Deputy Prime Minister of Greece (died 2014)

Ioannis Charalambopoulos was a Greek Army officer and socialist politician who served as Minister of Foreign Affairs and Minister of National Defence of Greece.

The Deputy Prime Minister of Greece is the second most senior member of the Cabinet. Despite the English translation of the title, he does not actually deputize for the Prime Minister, rather it is a mostly honorific post for senior ministers, and is usually combined with another senior government portfolio or a coordinating role over several ministries. The post is not permanent, rather it is created on an ad hoc basis, usually for the leaders of junior parties in coalition cabinets, and may be held by more than one person at once.
