Austria's two government coalition parties appeared to have lost some support in parliamentary elections Sunday but seemed likely to keep the absolute majority they need to stay in power for the next five years.

Meanwhile, a right-wing, anti-immigrant party made gains.

With more than 60 percent of the vote counted, the Socialist Party had 26.5 percent backing and its centrist People's Party partner was at 23.7 percent. That was a loss of more than 2 percentage points each for both parties.

A final official tally was expected later in the day.

The right-wing Freedom Party had 22 percent, a gain of nearly 4 percentage points, after a campaign strong on anti-immigrant and European Union-skeptic sentiment.

The Greens gained only slightly from the last elections five years ago, with 11.5 percent.

Also clearing the 4-percent hurdle needed to get into parliament were the liberal NEOS at 4.6 percent and the populist Team Stronach of Austro-Canadian billionaire Frank Stronach with 5.9 percent.

The partial results reflected some erosion of support for the mainstream Socialists and People's Party and their pro-EU stance, particularly in the context of the gains by the Freedom Party and Team Stronach's relatively strong showing in its first federal election.

Many Austrians are opposed to their government's financial and moral backing for the bailouts of Greece and other economically struggling eurozone countries during the protracted crisis that has gripped some of the 17 nations using the EU's common currency.
