A Malawi court is expected to rule on whether Madonna can adopt a second child in the country. Malawi's High Court will decide whether the pop singer should be granted an interim adoption of a four-year-old girl, Mercy James. On Thursday, Madonna received the backing of the southern African nation's government for her adoption bid. The administration came under fire after Madonna adopted a 13-month-old Malawian child, David Banda, in 2006, with critics accusing it of skirting laws to give her special treatment. Malawian information minister Patricia Kaliati said Madonna had helped in the country and was a worthy mother. She said: "Madonna has been good to us, she is supporting over 25,000 orphans in this country and she has proved that she can take care of David. "Very few rich and famous people can take time to fly all the way to Malawi to support our children - we support her adoption process." Malawi civil society groups oppose the adoption and a local human rights activist said it would amount to child trafficking. Madonna, accompanied by David, arrived in Malawi on Sunday ahead of the court examination of her application. The star, who was divorced last year from British film director Guy Ritchie, is one of the most successful singers of all time, with album sales of more than 200 million.
