Egyptian sources are dismissing reports that Gamal Mubarak and his family have left Cairo for London. If those earlier accounts were not outright propaganda, they seem to have been based more on wishful thinking than reality.The Mubarak regime is not as brittle as that of Tunisia s erstwhile president-for-life, Zine El Abidine Ben Ali, and right now seems to be in little danger of falling. However, it does seem to be the case that the protests erupting throughout Egypt s major cities are less about President Hosni Mubarak s 29-year-long reign than they are about the succession of the man who seems to be his chosen heir, his 47-year-old son Gamal.
