Egypt unrest sparks brain drain fear
Following the ousting of Hosni Mubarak in 2011, an increasing number of middle class Egyptians say they have considered leaving the country.
Concerns over basic state services such as education and security have pushed some to emigrate, while this month's unrest has done nothing to reassure those still considering their options.
The group most likely to pack up and leave include those with skills vital to Egypt's economy, sparking further worries about the nation's future.
