Austria's centre-left looked to have won elections in the city state of Vienna on Sunday despite the far-right increasing its score and recording its best-ever result in the capital, projections showed.

The Social Democrats (SPOe), which have ruled Vienna uninterrupted since 1945, scored 39.5 percent, down 4.9 points, while the Freedom Party (FPOe) rose 5.1 points to 30.9 percent.
