Zambia's deputy leader says President Levy Mwanawasa has undergone minor surgery in France to improve his breathing.

Zambian Vice President Rupiah Banda says Tuesday the president is in stable condition following the operation which took place Monday afternoon.

Mr. Mwanawasa suffered a stroke during a visit to Egypt on June 29 and was transferred to a Paris military hospital last week for treatment.

Mr. Mwanawasa is 59 years old and has served as Zambian president since 2002.  He suffered a mild stroke in 2006 before being re-elected that year.

Mr. Mwanawasa also is the leader of the Southern African Development Community.
