Malawi's Joyce Banda on President Mutharika's death
Malawi's government has confirmed that President Bingu wa Mutharika has died and declared 10 days of mourning.
Mr Mutharika, 78, suffered a cardiac arrest on Thursday and was taken to South Africa.
Medical and government officials said on Friday that he was dead but there was no formal announcement, leading to fears of a power-struggle.
Under the constitution, Vice-President Joyce Banda takes over and she has said the constitution will be followed.
