“Iron Lady” Margaret Thatcher has passed away at the age of 87. The news was announced by her daughter, Carol Thatcher, who said she died peacefully following a stroke on Monday morning.

Buckingham Palace issued the following statement:

“The Queen was sad to hear the news of the death of Baroness Thatcher. Her Majesty will be sending a private message of sympathy to the family.”

Current prime minister David Cameron said:

“It was with great sadness that l learned of Lady Thatcher’s death. We’ve lost a great leader, a great prime minister and a great Briton.”

Thatcher was the first female prime minister of Britain, and is often associated here in the U.S. with her work with former president Ronald Reagan in the 80s.

Here’s a small sample of the conversation in the Twitterverse:

It goes without saying (as it would for pretty much any politician), the world was divided on Thatchers politics, and that continues to be evident scanning the Twitterverse for reactions to her death. There are plenty of much more disrespectful reactions out there that we’re not going to include here.
