How long the meeting with the eldest son lasted is not known, but it is likely longer than Charles allotted to talk with Harry. It was also previously reported that his eldest grandchildren - Prince George, Princess Charlotte and Prince Louis spent some time with their grandfather, which clearly benefited the king.

The Welsh family was at the Anmer Hall estate last week, where they usually spend time with their children during the holidays. On Sunday, Prince William returned to London to attend the BAFTAs. Kate and the children probably still remained in Norfolk. It has not been reported that the princess plans to return to Windsor.
