The current leadership of the Muslim Brotherhood should quit and give an opportunity to the new generation who understands and estimates the national considerations and is aware of the times in which we live in, leader of the National Salvation Front Amr Moussa said. In an interview with the BBC\'s Hardtalk program on Thursday, Moussa said the Muslim Brotherhood should revise its policies and methods which they adopted and fueled the anger of the majority of the Egyptian people. The MB group is still enjoying the support of the Egyptian street, Moussa said. However, he added this support weakens and becomes less than that in the past. Moussa described as \"catastrophic\" the period during which deposed president Mohamed Morsi ruled in Egypt, saying this pushed up the Egyptian people to give vent to their anger and take to streets on June 30
