An appeals court in the Slovak capital has upheld a lower court ruling that Czech Finance Minister Andrej Babis did not collaborate with the communist-era secret police.

Babis, a Slovak-born billionaire businessman, was trying to clear his name and sued Slovakia's Institute of the Nation's Memory, which holds parts of his secret-police file. The institute said the file contains evidence that Babis was an agent.

But a lower court ruled in June last year that there was no proof for the allegation and Bratislava's regional court upheld that verdict on Tuesday.

The ruling is final.

Babis is a rising star in Czech politics. He leads the centrist ANO (YES) movement, which is part of the coalition government and currently the most popular political grouping in the Czech Republic.
