The Revolutionary Youth Union has called for Egyptians to head to Tahrir Square on 'Disenfranchisement Friday' to demand the exclusion of Mubarak-era prime minister Ahmed Shafiq from the presidential race.

The union, an umbrella for a wide spectrum of new political figures, also demands the implementation of the Political Disenfranchisement Law – which would bar Mubarak-era officials, including Shafiq, from holding political office.

The law was passed by parliament in April and is being examined by the Constitutional Court, with the verdict expected on 12 June.

Shafiq came second in the presidential election first round on 23-24 May and will face the Muslim Brotherhood's Mohamed Mursi in the second round slated for 16-17 June.

In a statement released Thursday, the union held Shafiq responsible for the Battle of the Camel which left 11 Egyptians dead during the Egyptian Revolution on 2/3 February 2011.

Ousted president Mubarak had recently installed Shafiq, an ex aviation minister, as prime minister in an attempt to quell the growing protests. However, only a few days later, thugs on horses and camels attacked protesters in Tahrir Square.

"Shafiq is the prime minister of the Battle of the Camel. He was a witness and a partner in the death of Egypt's pure youth. He was also a partner of Mubarak in destroying the political, economic and social life of Egypt," the union said in a statement on Thursday.

The union asked people to join the protests under the slogan of "No to a new Mubarak," a nod to the fact that many revolutionaries believe that if Shafiq becomes president he will resurrect the Mubarak regime. They also asked them to snub the results of the first round of the elections.

"The elections were rigged and forced people to choose between a member of the old regime or a Muslim Brotherhood candidate," the statement continued.

The union said it would participate in several marches to Tahrir Square as well as squares across Egypt to demand the disenfranchisement law be applied to Shafiq immediately.
