Dirhem Abdo Saeed is a member of one of Yemen’s most powerful families whose multi-billion-dollar global business empire began as a retail shop in 1938, in the British Protectorate of Aden. When the British were forced out of Aden in 1967 so was the Hayel Saeed Anam (HSA) Group who claim communists confiscated their assets. But HSA had protected itself, opening a global shipping company in the northern port of Hodeidah in 1962 and in 1969 establishing new headquarters in the city of Taiz, 17-miles south of Al Qaidah town. Dirhem Abdo Saeed opened HSA’s London office in 1977 and is a Honorary Vice-President of the British-Yemeni Society, established in 1993. The B-Y Society’s other Honorary VPs are an array of Establishment figures – diplomats and oil company executives. In 1995 HSA’s British supplier, my parent’s company JM Heaford Limited, was given a Queen’s Award for Export Achievement after furnishing a HSA Group factory near Taiz with some printing machinery. In 1997 HSA directors started using the British Cayman Islands tax haven and invested tens of millions of pounds creating Britain’s largest cardboard packaging company, Cepac Limited. And so it’s hard to exaggerate HSA’s links to the British Empire of old and to Britain’s Establishment of today. It’s also virtually impossible for me to exaggerate how complicit the HSA Group was in the greatest terrorist attack the world has ever seen – 9/11. I was with Khalid Sheikh Mohammed inside the HSA Group's Taiz headquarters on September 26, 1997 - where and when the 9/11 plot began.
