Faith in the government has eroded over the past couple of weeks due to its poor handling of the Sewol-ho ferry disaster.
With Prime Minister Chung Hong-won's resignation, there's mounting speculation a large-scale reshuffling of the Cabinet is on the way, to appease public anger and give the Park administration fresh impetus.
Political watchers say a number of high-level officials could get the chop including Security and Public Administration Minister Kang Byung-kyu, Education Minister Seo Nam-soo and Oceans and Fisheries Minister Lee Ju-young.
A number of ministers have come in for fierce criticism for their misconduct and remarks following the sinking.
The ruling Saenuri Party says a reshuffle will give momentum to reforms in the country to prevent a similar disaster occurring again.
A parliamentary committee has decided to deliberate on seven bills related to safety at sea, while the Saenuri Party plans to propose new bills to eradicate bureaucratic connections with related maritime industries.
The main opposition New Politics Alliance for Democracy is also preparing to unveil its own ideas on how to improve public safety.
As the June 4th local elections edge ever closer, President Park's tumbling approval rating could damage the Saenuri Party's chances.
The opposition party is expected to continue attacking the ruling party over Chung's resignation and its handling of the ferry disaster.
