The president of Mauritius, who was accused of using a credit card issued by a charity to buy clothes and jewelry worth tens of thousands of dollars, will step down, the prime minister announced on Friday.

Prime Minister Pravind Jugnauth told reporters that Ameenah Gurib-Fakim, the first female president of the island nation off the east coast of Africa, would resign after Monday, when the country marks its 50th anniversary.

“The president of the republic told me that she would resign from office and we agreed on the date of her departure,” Mr. Jugnauth said in Port Louis, the capital, according to the BBC.

He did not provide the exact date of her departure, but he said her resignation would take place before Parliament returns at the end of the month.
