President Muhammadu Buhari has received newly-posted Ambassador of Greece to Nigeria, Mr Ioannis Plotas.
He arrived at the Presidential Villa, Abuja, to meet the usual reception ceremonies, beginning about 11am on Tuesday.
Plotas came to formally present his Letters of Credence to Buhari.
However, much of the interface between the President and the envoy took place behind closed doors.
Buhari also received the envoys of Cuba and Equatorial Guinea on a similar mission to present their L of C.
