lololol:
"The drama claimed that Benoist is the only tea company to hold a set of three Royal Warrants, specifically by Her Marjesty the Queen, HRH The Prince of Wales, and HM the Queen Mother. However there is no evidence to support this claim, and a search of the Royal Warrant Holders Association website reveals this to actually be true of R. Twining & Co."
