Britain's Prince William turned 28 on Monday, passing an unofficial "deadline" he had once set himself to marry Kate Middleton, his long-standing girlfriend, DPA reported.
The prince, who returned from a trip to Africa on Sunday, resumed his training to become a Royal Air Force search and rescue helicopter pilot at a base on the island of Anglesey, in the Irish Sea on the west coast of Britain. He is due to complete his course in September.
William, second-in-line to the throne, suggested several years ago that he believed the late 20s were the right time to marry. "I don't want to get married until I'm at least 28 or maybe 30," he said.
His relationship with Middleton, whom he has been dating since they were at university together in 2003, seems as strong as ever, reports said.
But despite much speculation there is no sign of a royal engagement.
William, and his younger brother, Harry, returned from a joint 10-day trip to southern Africa on Sunday, which included visits to charity projects in Botswana and Lesotho.
They also travelled to Cape Town to watch the England-Algeria World Cup match - reportedly cheering up the England team - which ended in a disappointing 0:0 draw. William is president of the Football Association.
