The Muslim Brotherhood has condemned army chief Abdul Fattah al-Sisi’s decision to run for the Egyptian presidency.

The movement says Sisi has undermined the goals of the original revolution in 2011 that overthrew former president Hosni Mubarak.

The official statement follows Egypt’s military authority, the Supreme Council of the Armed Forces (Scaf), approval of Sisi’s presidential bid on 27 January.

The news comes after months of speculation about Sisi’s presidential ambitions.

Earlier in January Egypt held a referendum on a newly amended constitution that was passed with 98 per cent approval.

The interim government has also brought forward the presidential elections ahead of the planned parliamentary elections,. The schedule now differs to the plan originally set out by the interim government following the ousting of former president Mohammed Mursi last July.
