She has no formal political role, but Queen Elizabeth II has been named Britain's most powerful woman by a BBC radio program.
The monarch topped the list of 100 female figures announced Tuesday on "Woman's Hour."
Home Secretary Theresa May — Britain's interior minister — ranks second, followed by Ana Botin, chief executive of Santander U.K. bank.
The top five also includes Supreme Court judge Brenda Hale and Elisabeth Murdoch, chair of television company Shine Group and daughter of media mogul Rupert Murdoch.
The list was assembled by a panel that included journalist Eve Pollard, lawmaker Priti Patel and crime novelist Val McDermid.
Among those omitted was the former Kate Middleton, wife of Prince William. Pollard said the judges felt Kate had enormous influence — but not, yet, power.
