This is what everyone has been expecting, so no surprise. Egypt still receives billions of dollars per year from the US, so how much will that relationship really change? It's possible, but someone will need to cough up a few billion per year to fill that gap or else Egypt's problems will be much worse. The Guardian:
The final results in Egypt's first parliamentary elections since the overthrow of Hosni Mubarak have confirmed an overwhelming victory for Islamist parties. The Muslim Brotherhood, which was banned under Mubarak's regime, won the biggest share of parliamentary seats (38%), according to the High Elections Committee. Its Freedom and Justice party (FJP) has named Saad al-Katatni, a leading Brotherhood official who sat in the old parliament as an independent, as speaker of the assembly. The hardline Islamist Al-Nour party came second with 29% of the seats. The liberal New Wafd and Egyptian Bloc coalition came third and fourth respectively.
