LONDON (AFP) - Pop megastar Michael Jackson will testify in person at London's High Court next week against allegations that he owes a Bahraini prince seven million dollars, his lawyer said Thursday. Robert Englehart, representing the "King of Pop", told the court that Jackson was withdrawing his application to give evidence via videolink from Los Angeles because of health concerns. "He has been cleared by his medical advisers to travel in two days' time," Englehart said. Sheikh Abdulla bin Hamad Al Khalifa, second son of the King of Bahrain, is suing cash-strapped Jackson for seven million dollars (5.6 million euros), demanding the repayment of several advances which the artist has argued were gifts.
