Former British Prime Minister Margaret Thatcher will receive a “ceremonial funeral” with military honors at St Paul’s Cathedral, Prime Minister David Cameron’s office announced Monday.

The service will be followed by a private cremation, in accordance with the wishes of Thatcher’s family, the prime minister’s office said.

The date and timing of the service will be announced later.

“Today is a truly sad day for our country,” Cameron said in a statement that was broadcast by the BBC. “We’ve lost a great prime minister, a great leader, a great Briton.”

“As our first woman prime minister, Margaret Thatcher succeeded against all the odds. And the real thing about Margaret Thatcher is that she didn’t just lead our country, she saved our country, and I believe she’ll go down as the greatest British peacetime prime minister.

Former President George W. Bush called Thatcher “an inspirational leader who stood on principle and guided her nation with confidence and clarity. ... a great example of strength and character, and a great ally who strengthened the special relationship between the United Kingdom and the United States.”
