Hundreds of protesters rallied against a ball in Vienna on Friday, an event organised annually by the anti-immigrant Freedom Party (FPO), junior coalition government partner to Chancellor Sebastian Kurz's conservatives.
The turnout for this year's protest was estimated at 1,600 by police and 3,000 by organisers, both smaller than last year when more than up to 10,000 marched against the Academics' Ball, coming a month after the FPO joined Kurz's coalition government.
A police spokesman said there were no incidents and "everything passed very calmly".
The ball, which took place in Vienna's former imperial Hofburg Palace and draws protests every year, has in the past attracted right-wing icons such as France's Marine le Pen.
Many in the protests held placards and banners with the slogans saying: "Don't let the Nazis rule" and "Down with the government of the rich".

- Holocaust facts: Where does the figure of 6 million victims come from?
The organisers of protest, named "Offensive Against the Right", said the ball was a celebration of "authoritarian reorganisation of the country" in a statement on its Facebook page.
