"Our government resigned in order to pave the way for transition to a new government dealing with popular changes; however, obstruction has continued for 90 days and the country is moving toward the unknown," Hariri said in a tweet on Monday.
"The continuation of the caretaker government is not the solution so let's stop wasting time and have the government bear the responsibility," he added.
Since October, Lebanon has been rocked by nationwide protests against rising inflation and living costs as the government struggles to attract investment amid increasing economic hardships and a decreasing capital flow to the country.
Hariri's Monday remarks echoed his similar call on Sunday, when he asked the country's politicians to urgently form a new government and “stop wasting time” to find solutions for the Lebanese economic crisis in order to “calm the popular storm.”
“We feared for Beirut yesterday, but as usual, it has stitched the wounds of its sons from the ranks of the security forces and protesters and removed from its face the remains of anger, rioting and the smoke of blazes,” Hariri wrote on his official Twitter page on Sunday, after a night of violent clashes between security forces and protesters.
