The Democratic Coalition ( DK ) stated immediately after Orbán 's announcement that the party will boycott the referendum . According to '' Népszabadság '' , party leaders Gyula Molnár ( MSZP ) and Ferenc Gyurcsány ( DK ) agreed that both parties will use the same slogan : " Stay at home , Stay in Europe ! " . However Socialist spokesperson István Nyakó nuanced the journal 's information : " There is agreement in this issue , but there is no co-operation " . Gyurcsány argued in September 2016 , that the government considers the referendum as an " early parliamentary election " . He added , " there is no governance for years " and the cabinet intends to hide the existing economic difficulties under the migrant issue and the quota referendum campaign . According to Gyurcsány , the Fidesz leads Hungary to a " historic blind alley " . On 16 September , Gyurcsány claimed the Fidesz government will initiate an early parliamentary election , if the quota referendum will be valid . He said Orbán " builds a new political community through fear and hate campaign ... " . Few days later , Gyurcsány told that he received this information from the inner circle of Prime Minister Orbán . During an interview , Orbán refused Gyurcsány 's allegations . The Prime Minister said " early parliamentary election is often a sneaking matter " . The Democratic Coalition published its own campaign song in September 2016 , the chorus was " Do not say no , do not say yes , the answer does not mean anything , if the question is liar " . One day before the September 2016 Budapest explosion , board member György Kakuk called on the government not to perform any simulated bomb attack in order to increasing willingness to vote . He compared the government 's " hate campaign " to pre-1945 era . The party held a peaceful demonstration in front of the Hungarian Parliament Building on 1 October , when thousands of DK sympathizers joined their hands to form a human chain around the building . Gyurcsány said during the event that the government is trying to " steal the greater part of the honesty of Hungary , however the democratic opposition will be able to prevent that " . Far-right elements sought to prevent the demonstration , but they failed , when DK supporters sang '' Himnusz ''
