Stroking a coalition deal, however, won't be easy.
ANO strictly opposes plans by the Social Democrats to increase corporate and personal income taxes for those in the highest bracket.
Babis said higher taxes are "no solution for us." He said better governance, tax collection and savings would be a better way to improve the state's finances.
Babis campaigned on an anti-corruption ticket and attracted a surprisingly high number of voters who were disgusted by corruption scandals and didn't care about reports denied by Babis that he collaborated with the communist-era secret police.
The election was called to end a political crisis triggered by center-right government's spectacular collapse in a whirlwind of corruption allegations and marital infidelity.
The Social Democrats also want to abandon pension and health-care reforms adopted by the previous government and at least modify legislation to pay billions to religious groups in compensation for property seized by the communist regime.
Sobotka called the compensation "too generous" but the Christian Democrats, as well the country's churches, oppose any changes.
