Sir Robert Milton Worcester, (21 December 1933 – 5 September 2025) was an American-born British pollster who was the founder of MORI (Market & Opinion Research International Ltd.) and a member and contributor to many voluntary organisations. He was a well-known figure in British public opinion research and political circles and as a media commentator, especially about voting intentions in British and American elections. A Kansas City native, Worcester graduated from the University of Kansas in 1955, and following service in the US Army Corps of Engineers in Korea worked with management consultants McKinsey & Company. In 1965, Worcester joined Opinion Research Corporation as chief financial officer before coming to Britain in 1969 to found MORI, then a joint-venture of ORC and National Opinion Polls, becoming the principal owner four years later. In the 1970s MORI was appointed the Labour Party’s opinion pollsters and Worcester therefore acted as advisor to the then Prime Minister, James Callaghan.
