What happened

Why it matters

Claim 1: “The late queen was the only person in history to have ever eaten a chocolate bar made with 100% British ingredients, after she was given one as a six-year-old in 1932 by the confectioner Rowntree’s.”

SINGLE SOURCE

While multiple sources confirm that Rowntree's made a UK-grown chocolate bar in 1932, none of the provided evidence explicitly mentions that Queen Elizabeth II was the only person to eat it or that she received it as a six-year-old. The evidence confirms the 1932 date and the company, but not the specific royal anecdote.
