Prince William and Princess Catherine are to set off on a world tour next year. The couple, who married at London's Westminster Abbey on Friday, April 29, will make official visits to Australia, New Zealand and the Caribbean, as well as other Commonwealth countries in Africa and Asia, to ease Queen Elizabeth's workload in her Diamond Jubilee year.

With the queen reportedly having told fellow members of the British royal family they must rally round as she celebrates 60 years on the throne, it is thought Buckingham Palace officials are hoping to capitalize on the success of Friday's nuptials, which were watched by an estimated two billion people worldwide.

A Palace source told The Sun newspaper, "Demand for William and Catherine is expected to go through the roof following the incredible reaction to their wedding. They are keen to settle into married life and only plan the minimum of official engagements. But the Jubilee is different.
