London: Since their public rift at the funeral of Diana, Princess of Wales six years ago, the royal family and the Spencer family are to be united for the first time.

The Prince, who comes of age on June 21, is determined to hold an "inclusive" celebration which his father the Prince of Wales and his grandmother the Queen, who will attend along with Earl Spencer, his mother's brother, and his mother's two sisters, says a report in 'The Telegraph'.

Relying on the prince's maturity and wisdom, palace officials hope that the evening of his 21st birthday at Windsor Castle next month will mark the end of years of private and, at times, open hostility between the two families.

According to the report, tensions between the Windsors and the Spencers began when the marriage of the Prince and Princess of Wales disintegrated in the 1980s.

Prince Charles and the Queen were consulted over the guest list for the party, but it ultimately boils down to Prince William to take a decision. The party has an "Out of Africa" theme. Camilla Parker Bowles, Prince Charles's companion, has been invited to the party and has accepted.
