"The corruption has been raging for decades and will not be overcome if we do not unite our efforts … The people’s rights and trust have been lost. This is a big problem and we must restore this trust," Aoun said, addressing his followers in the city of Baabda.
The Lebanese government resigned this week after 13 days of protests over economic hardships. Outgoing Prime Minister Saad Hariri has been asked to perform his duties until the new government is formed.
The country's leader also thanked his followers for their support.
The protests in the country were sparked by the authorities' intention to introduce a tax on online calls as well as poor economic conditions and low living standards. The plans for the additional levies have since been dropped but the protests continued. The unrest resulted in further deterioration of the economic situation.
