His government, which was supported by Hezbollah and its allies and seen as one-sided, was basically doomed from the start, tasked with meeting demands for reform but made up of all the factions that reformers want out.
Now the process must start again, with Diab’s government in a caretaker role as the same factions debate a new one.
“I hope that the caretaking period will not be long because the country cannot take that. Let's hope a new government will be formed quickly,” Public Works Minister Michel Najjar told reporters. “An effective government is the least we need to get out of this crisis.”
The weekend protests saw clashes with security forces firing tear gas at protesters.

The explosion is believed to have been caused by a fire that ignited a 2,750-ton stockpile of highly volatile ammonium nitrate.
The material had been stored at the port since 2013 with few safeguards despite numerous warnings of the danger.
The result was a disaster Lebanese blame squarely on their leadership’s corruption and neglect.
Losses from the catastrophic blast are estimated to be between $10 billion to $15 billion, with nearly 300,000 people left homeless.
The last decision taken by Diab’s government before its resignation was to refer the case of the explosion to the Supreme Judicial Council, which handles crimes infringing on Lebanon’s national security as well as political and state security crimes.
