MEXICO CITY, Sept 11 (Reuters) - Margarita Perez, the

head of the commercial arm of Mexican state energy company

Pemex, has left her position and will be replaced by finance

ministry official Adan Garcia, a spokesperson for the company

said on Thursday.

Reuters reported the news earlier based on information from

four sources and one internal email.

PMI Comercio Internacional, as the entity is known, is

responsible for importing refined fuels into Mexico and

exporting crude oil, mainly the country's flagship Maya.

The Pemex spokesperson said that Garcia's appointment is set

to be discussed on Friday at a meeting of the oil company's

board of directors.
