The ruling New Democracy party has extended its lead over main opposition Pasok, according to a GPO poll, though the advantage comes amid a sharp rise in undecided voters that signals growing volatility in the political landscape.
While support for New Democracy dipped slightly to 24.5% from 25.2% in November, Pasok suffered a steeper decline, falling to 10.8%.
The shift leaves Prime Minister Kyriakos Mitsotakis with a comfortable margin, even as nearly one in five voters (17.9%) now describe themselves as undecided.
The survey, conducted for Star TV, highlights the rising influence of non-traditional forces. The far-right Greek Solution polled third at 9.6%, followed by Course of Freedom at 8.2%.
A potential wildcard has emerged in Maria Karystianou.
The poll found that 20.1% of respondents are likely to vote for a party led by Mrs. Karystianou, drawing interest primarily from anti-establishment and undecided blocs.
Meanwhile, 17.6% expressed willingness to support a new movement led by former Prime Minister Alexis Tsipras.
Voter sentiment remains heavily influenced by economic strain.
High prices were cited as the top concern by 58.5% of respondents, with half stating their income no longer covers monthly expenses.
On foreign policy, the poll reflected deep skepticism regarding U.S. politics.
Over 76% said President Donald Trump’s interest in purchasing Greenland weakens European security, and a majority opposed Greece joining Mr. Trump’s proposed "Peace Council."
