Opposition parties have had a boost in support compared to November, according to a new poll conducted for Yle.
The National Coalition Party (NCP) tops the December poll, with pollsters estimating that they get some 21.8 percent of voters' support.
The last time the NCP polled this well in Yle's survey was in 2017. The jump on November's figures is around one percentage point.
In second spot is the Finns Party, which pushed the Social Democrats into third spot.
The Green League is on 10.1 percent, a drop of 1.3 percent on November despite the drawn-out reshuffle following leader Maria Ohisalo's departure for maternity leave which saw new roles for four of their other biggest names.
