Ambassadors and Consuls

An ambassador is the foreign diplomatic representative of a nation who is authorized to handle political negotiations between his or her country and the country where the ambassador has been assigned, while a consul is a commercial agent of a nation, who is empowered only to engage in business transactions, and not political matters in the country where he or she is stationed. 

A consul is not entitled with the privileges accorded to an ambassador in the exceptions provided under article 2 of the Revised Penal Code.
