The ruling Saenuri Party welcomed the president's address, particularly her pledge to move forward with revising the Constitution, which currently stipulates a single five-year term for presidents.
The party said now is the time to start discussing the matter, to reflect both the changes in society and the challenges of the future, and it vowed to gather public opinion on the issue.
"The Saenuri Party vows to faithfully take up the revision issue by listening to experts and the public.. for Korea's bright and hopeful future."
The main opposition Democratic Party of Korea criticized the president's sudden change in stance on the issue.
It said it cannot accept the revision proposal now, when the top office is mired in corruption allegations.
"President Park flatly rejected the (Constitutional) revision two years ago. She said it would ruin the economy, because revision discussions would eclipse every other issue like a blackhole. She made the issue taboo. Thus we cannot accept the authenticity of the revision proposal."
The minor opposition People's Party said it welcomes the revision, but it, too, was critical of the move.
Echoing the main opposition party, it questioned the president's timing and asked why the Presidential Office would move forward with the revision now, after having ignored the opposition bloc's requests for so long.
"It's a bit fishy that the president would propose a revision at this time, because it seems that the Presidential Office would want to cover up the recent string of corruption allegations against it."
"The party added that a Constitutional revision is not a cure-all, and not every problem in the nation's political realm has originated with the document. It concluded by urging the top office and ruling party to focus on more urgent issues.
