Princess Diana is facing a heartbreaking future, increasingly cut off from her sons. Buckingham Palace is tightening it's grop on Wills and Harry's lives to limit her influence on them. Although Di will share custody of the boys in her seperation from Charles, they will spend less time with her as they are groomed to become senior members of the monarchy. A close family friend said: "The days of her constant contact with her sons are coming to an end. She will have custody, but it will be rather limited custody." Royal expert Harold Brooks-Baker said: "Prince William has a future as the heir to the throne and there is very little the Princess of Wals can teach him about that. Prince Harry will follow the same path. Only their father and hi family can teach them that, and the Princess's influence will become marginal." Di's influence that the boys lead as normal a life as possible is at odds with the palace. The boys regularly quene with their mum at McDonald's in Londond's Kensington High Street. But a friend said: 'How much use that will be to them in the future is doubtful. The point is that they are not ordinary people. The marriage didn't break down because Prince Charles was unable to accept that fact that they are differnet people with different rules." Di told friend before she flew on her post-Christmas Caribbean holiday with Wills and Harry that they were "the only men in my life who haven't let me down." -by Clive Goldman and Alan Hart (News Group Newspapers Ltd., January 10, 1993)
