Maronite Patriach Beshara al-Rai accused the Lebanese authorities of creating a political vacuum by leaving the presidency unfilled with outgoing president Michel Aoun's term ending on Monday.
Al-Rai said in his Sunday sermon that officials had "left this supreme and essential presidency in a vacuum, either deliberately, or out of stupidity or selfishness."
He described the presidency as a “cornerstone” for the unity of the state.
The “presidential vacuum in Lebanon is not a fate but rather a conspiracy,” al-Rai cautioned.
Aoun left the presidential palace in Baabda on Sunday, a day ahead of the official end of his six-year term but without a successor.
Aoun leaves the fragile country in an unprecedented situation where the presidency is vacant at the same time as the cabinet operates in a caretaker capacity.
