For 11 years, with an intensity that earned her the nickname the "Iron Lady", Magaret Thatcher ruled Britain as the country's first female prime minister.
During her time in power, Thatcher earned both admirers and opponents as a result of her conservative politics.
Her life is now the subject of a Hollywood film premiering in London and starring Meryl Streep.
The filmmakers have said the movie is not about only politics, but also about a formidable woman brought down by old age.
