The party, led by incumbent President 67-year-old billionaire Andrej Babis, received about 30 percent of the vote when half of the districts were counted.

This despite the fact that the president was in bad weather ahead of the two-day election that took place on Friday and until 12 o'clock on Saturday.

Babis was recently accused of hiding large sums of money in a tax haven and for buying a castle in the south of France.

The information was discovered when the leaked so-called Pandora documents were published.

After Ano comes the bourgeois alliance Together, with just over 24 percent of the vote.

A new political coalition with, among other things, the anti-establishment movement Piratpartiet has received just under 14 percent.

The early forecasts usually come from smaller, rural districts that previously voted for Ano to a greater extent than urban voters.
