From a letter written on behalf of April 6 to the European Union:
On 10 February 2014, the Foreign Affairs Council Meeting concluded in point 8: "The EU also reiterates its readiness to observe the upcoming elections, if conditions are met, and calls on the Egyptian interim authorities to ensure an environment conducive to inclusive, transparent and credible elections, including a level playing field for the election campaigns. In view of the recent developments, the Council recalls that no political groups should be excluded or banned as long as they renounce violence and respect democratic principles".
In times in which more than twenty thousand prisoners are detained since the military intervention/coup on 3rd July, political movements, Islamist and Secular, are being banned, extreme nationalistic propaganda are widely diffused through the State apparatus, it is quite evident that the "conditions are hardly met". It is certain that Mr. Sisi will win the show, whether in presence or absence of the EU elections observation mission. Suspending the mission, however, would send a clear message to Mr. Sisi as well as to the European and Egyptian public opinions that the EU can hardly accept and even participate in legitimizing the current practices in Egypt.
