Article 65 of the Egyptian constitution guarantees freedom of thought and opinion - but the EU criticised Egypt after observing an alleged lack of respect for these rights on the ground, leading to a climate of limited free expression and journalistic self-censorship.

It also said that Egyptian government officials acknowledged that authorities have detained more than 16,000 individuals, including 1,000 protesters, since January of this year.
