LONDON (AP) — A legal battle between the powerful, poetry-writing ruler of Dubai and his wealthy estranged wife is leading toward a showdown in a London courtroom later this month.

The family division court case scheduled on July 30 pits Sheikh Mohammed bin Rashid Al Maktoum against Princess Haya, daughter of the late King Hussein of Jordan and an accomplished Olympic equestrian on friendly terms with horse aficionado Queen Elizabeth II.

The hearing is expected to focus on who will have custody of their two young children now that the princess has left Dubai. She is believed to be in Britain, where she owns a gated mansion on Buckingham Palace Gardens, a private street lined with some of the world's most expensive homes and cars.
