Mayor Istvan Tarlos, Prime Minister Viktor Orban, and Zsolt Borkai, the head of the Hungarian Olympic Committee, agreed late Wednesday on the withdrawal after it became clear the project would have to face a city-wide referendum initiated by the Momentum Movement, a new political group. The government, which decided on the withdrawal even though election officials have yet to officially sign off on the referendum, blamed the opposition parties, most of which earlier backed the Olympic project, of "dismantling national unity." Speaking on state radio, Orban branded the Momentum Movement as "dream-killers," saying they initiated the referendum for their own political gain.
