UNDATED (CNN) -- People from all over the world are reacting to the death of former British Prime Minister Margaret Thatcher's death.
London Mayor Boris Johnson says, "I think this country has just lost it's greatest Prime Minister since Winston Churchill and Margaret Thatcher was a revolutionary and a liberator. She freed millions of people to buy their own homes, to buy their own shares in British companies. And yes, sometimes some of the things she said were tough, but I think when you look back she was overwhelmingly right in her judgment."
