The new get-tough approach has the full support of the Prince of Wales, Prince William, Prince Harry and other senior members of the Royal family, who are now prepared to take legal action against what they see as the "intrusive and unacceptable behaviour" of photographers.
The new strategy is likely to be tested later this month when the Queen, accompanied by other members of the
Royal family, enjoys her traditional Christmas break at Sandringham, her Norfolk estate.
Several freelance photographers usually spend many hours a day touring Sandringham in the hope of "snatching" photographs of the Royal family on the estate.
However, senior aides at both Buckingham Palace and Clarence House have told
The Sunday Telegraph that they will no longer tolerate photographers using telephoto lenses to capture pictures of the Royal family in "private" situations.
Until now, the Royal family has, reluctantly, turned a blind eye to such photographs provided they were taken from public roads and they did not involve trespass on private land.
