Belgium's King Philippe has met his once secret half-sister Delphine de Saxe-Cobourg for the first time, the palace said Thursday, after she won a legal battle to be admitted to the royal family. The meeting took place on October 9 and led to a "long and rich exchange" that will allow the relationship to develop within a "family framework," said the statement, signed "Phillipe and Delphine." mad/dc/arp/txw
