Imelda Marcos was 90 this week. Although I knew her once, I hadn’t thought about her for many years and assumed she must be dead. Then I read that 200 people had been rushed to hospital with food poisoning at the party she gave to mark her big birthday in a football arena in the Philippines. She simply can’t keep out of the news. She is probably the biggest plunderer in the history of the world, having salted away up to $10 billion, much of it in property in New York, in jewellery and paintings, while First Lady of the Philippines for 21 years from 1965-86.
