Chad’s President Idriss Deby has sacked Finance Minister Christian Georges Diguimbaye a government decree showed.

According to the decree, Abdoulaye Sabre Fadoul, the minister-secretary general of the government in charge of institutional reform, will serve as interim finance minister.

The decree also dismissed Diguimabye’s deputy, Banata Tchalet Sow, Reuters news agency reports.

Diguimbaye and Sow’s dismissal came amid a standoff with Swiss-based commodities giant Glencore over more than $1 billion the West African country owes it in oil-backed loans.

Chad is under pressure to restructure its debt to Glencore for a second time after the International Monetary Fund said this year that its external commercial debt was unsustainable.
