Kensington Palace has issued a statement following reports of a letters warning against "acts of harassment" of the Duke and Duchess of Cambridge at their Norfolk home have been distributed by police.

Norfolk Police confirmed that officers had been asked to hand out leaflets, while the Kensington Palace said they were given to people found to be breaking the guidance.
The statement said: "This is a letter given by police to individuals found operating on or around the Sandringham estate, including Anmer, on behalf of the Royal Household.

Letters warning against "acts of harassment" of the Duke and Duchess of Cambridge at their Norfolk home have been distributed by police.
Kate and William left London for Anmer Hall, on the Queen's private Sandringham estate, with their new baby Princess Charlotte and her elder brother Prince George yesterday.
According to reports letters were given to media by Norfolk Police stating that while the Cambridges are in residence they have "a more than reasonable expectation of privacy".
The letter, undersigned by the couple's communications secretary, called for "acts of harassment and breaches of privacy to cease".
It said: "There have in the past been a number of intrusions into the privacy of the Royal Family which in the main have been as a result of professional photographers using long-distance lenses, not only to observe the Royal Family, but also to photograph them going about their activities on the estate."
Previous warnings to photographers meant "the position has greatly improved".
But it continued: "However, we would remind you again of the position. The Sandringham Estate trusts that there will not be a need to take any further action other than bringing these points to your attention."
