Christian Democrat leader Göran Hägglund and Jan Björklund of the Liberal Party were also visiting Gothenburg.
The re-vote for Örebro city council and Västra Götaland county council is taking place today due to miscounts in very close run seats in last Spetmebr's elections.
A record number of complaints were received by the review board over vote counting discrepancies in the 2010 national and local elections.
There were votes that never got counted and faulty votes that had been counted. In Örebro, volunteering election workers from one party accompanied voters into the polling station, which is strictly forbidden, and in Västra Götaland, three voters were declined to vote even though they had the right to do so.
