A family-run ice cream shop has been forced to change the name of its Percy Pig ice cream after M&S sent a cease and desist letter - with a packet of sweets.
Fabio's Gelato, based in Hitchin, Hertfordshire, received the letter after making the unique ice cream for only a week.
Marks said owner Fabio Vincineti could not use the name of the product - as since 1992 Percy Pig could only be used on "official M&S products".
