The Pirates, Praha sobě and United Forces (TOP 09 and a few minor parties) are currently negotiating a coalition. And all three of them want the position of mayor - Pirates' Zdeněk Hřib because they as a party won the most votes, Praha sobě because their candidate Jan Čižinský won the most preferential votes and TOP 09 because their candidate Jiří Pospíšil has the most political experience.
