The Center Party lost supporters while the Reform Party's popularity grew, January's ERR-commissioned TNS Emor opinion poll revealed.
If the general elections were held tomorrow, the Center Party would get 25 percent of the vote - a steep drop from its 32 percent last month. The biggest gainer was the Reform Party, which rose five percentage points to 24 percent to take second place.
The Social Democrats' support stayed the same - 23 percent. IRL is in fourth place, but their support is 22 percent, up from 20 percent last month. IRL had been just over 10 percent less than a year ago.
This is the greatest amount of parity that has existed in years between the four parliamentary parties.
Undecided voters amounted to 34 percent - lower than in previous months.
