The National Coalition Party leads Yle's final party support poll before the local elections with 19.6 percent support.
In second spot was the Finns Party with 18 percent, and in third spot were the Social Democrats on 17 percent.
The Social Democrats dipped the most in the poll, with their support dropping by 1.1 percentage points in a period when the party was embroiled in a scandal over Prime Minister and SDP leader Sanna Marin's breakfast expenses.
The Finns Party dipped 0.2 percent, with a scandal about party election posters targeting immigrants in social housing hitting the headlines during the same period.
The Centre party gained the most in this poll, with their support increasing by 1.3 percent.
That is however within the poll's 1.9 percentage point margin of error.
Taloustutkimus interviewed 2,965 people between 5 May and 8 June.
