On one issue many Britons would still agree with Thatcher: Her stubborn rejection of the notion of the euro, Europe's common currency, when it was first being considered in the 1980s.
The euro has for the past three years been in crisis as its members struggle with excessive debt and no longer have a national currency to devalue to regain competitiveness for their exports. Thatcher famously rejected any notion that Britain might give up the pound and was a tough negotiator with European leaders in Brussels.
EU Commission President Jose Manuel Barroso, offered sadness at her passing, but even he had to note her willful point of view.
"She will be remembered for both her contributions to and her reserves about our common project," he said.
