Nobel laureate and liberal Egyptian leader Mohamed ElBaradei is facing charges of dishonesty following his resignation as the vice president amid spiralling unrest.

The Nasr City Misdemeanour Court will convene in September to consider the lawsuit filed against ElBaradei.

The case has been filed by Sayed Ateeq, chief of Criminal Law Department at Helwan University's Faculty of Law.

Ateeq said ElBaradei was chosen as a representative of National Salvation Front and not on his personal capacity. The case has been filed following his failure to represent the view of opposition bloc while disregarding the "terrorist crimes" committed by Muslim Brotherhood which is a breach of "national trust", said Ateeq.

He added that the liberal leader did not consult with the Front regarding his resignation. ElBaradei stepped down last week after the crackdown by security forces led to severe bloodshed killing dozens.

ElBaradei's stepping down has sent out a wrong image about Egypt to the outside world and has damaged the reputation of the interim administration, Ateeq said.

ElBaradei currently is in Austria along with his family.
