Russian President Vladimir Putin was a guest at the Austrian foreign minister's wedding on Saturday. It is a move that opposition politicians say undermines the European Union's position on Moscow.

Putin dropped in on Karin Kneissl's wedding in a remote area of southern Austria. This on his way to a meeting with Chancellor Angela Merkel in neighboring Germany later that day.

CNN reports that the Russian president was pictured dancing with Kneissl, who was dressed in a traditional "dirndl" dress, in a vineyard in Styria province.

According to Russian state-run news agency TASS, Putin arrived with a bouquet of flowers and even brought a Cossack choir with him to entertain the bride and her groom, the entrepreneur Wolfgang Meilinger.
