Egypt's interim prime minister, Kamal El-Ganzouri, has written a letter to the Parliament Speaker Mohamed Saad El-Katatni asking him to postpone a summons against him in relation to ongoing investigations into the foreign NGO controversy.

Parliament had set Sunday for an investigation session with Ganzouri and relevant ministers, focusing on the government's role in lifting a travel ban on the accused in the case probing foreign funded NGOs and their activities. The ban lifted, many departed Egypt.

Ganzouri's letter to El-Katatni reportedly stated that the government is ready to address parliament on issues related to NGOs receiving foreign funds, but not while a lawsuit is ongoing before a judicial body.

A group of Ganzouri's ministers, however, did attend Sunday's parliament session to address MPs' questions on the case that caused wide public uproar and pushed parliament to the point of mulling a no confidence vote against Ganzouri's government.

Fayza Aboul Naga, minister of international cooperation who initiated the case against the NGOs, attended the parliament session along with Mohamed Ateya, minister of parliament affairs.
