Britain's newspapers have played their annual April Fool's jokes on their readers with a series of hoax stories.

"The Sun" reckons gipsies have established a camp on the Queen's grass at Windsor Castle using a 650-year-old law. The paper reckons the gipsies claim to be descended from the original builders of the castle who got permission to put their tents there from King Edward III.

"The Mirror" reckons sheep with St George's Cross markings on their coats are being used to cut the grass at the new Wembley football stadium. It says the natural fertiliser of their droppings has reduced the need for chemicals, meaning less allergic reaction on players. The paper claims a Wembley spokesman said: "It's based on methods going back centuries."

Meanwhile "The Daily Mail" has what it claims to be a 'Royal picture exclusive' of Prince Charles and Prince Harry shopping for sexy underwear. The pictures show Royal look-alikes examining bras and knickers at what is described as an exclusive lingerie shop near Windsor Castle.
