Britain's Sky News is reporting that the nations first and only female Prime Minister, Margaret Thatcher, passed away Monday morning (April 8) at the age of 87 from a stroke.  Thatcher served as Prime Minister from 1979 to 1990.

Her friendship with President Ronald Reagan helped forge a tough alliance between the U.S. and Great Britain at the very height of the Cold War.  It was this alliance that helped lead to the collapse of the Soviet empire.

Thatcher had become much less of a public figure in recent years due to frail health.
