The first female prime minister of England, Margaret Thatcher, has passed away due to a stroke. She was 87 years old.

A spokesperson for Thatcher confirmed that she has passed away. They say that a further statement will be made later. She reportedly died Monday morning after suffering a stroke.

SkyNews reports that Thatcher was very frail in recent years, and was suffering from health issues. She was admitted to the hospital just before Christmas to remove a growth in her bladder. She suffered a series of small strokes in 2004, and her health was seemingly on the decline ever since.

Thatcher was Britain’s first, and only, female prime minister. She served in the role between 1979 and 1990.
