An appeals court has canceled the acquittal of the wife of former Czech Prime Minister Petr Necas of abuse of power charges in a case that brought down his government.

In May, the Prague 1 district court acquitted Jana Necasova, formerly Jana Nagyova, two former heads of the military intelligence agency, Ondrej Palenik and Milan Kovanda, and an intelligence agent. Prosecutors appealed, and all four will get a new trial.

Prosecutors charged that Nagyova — then Necas' chief of staff and mistress — ordered the military intelligence agency to spy on Necas' estranged wife in 2012.

Marketa Puci, spokeswoman for Prague's Municipal Court, said Thursday the case now returns the lower court.

After his government fell in June 2013, Necas admitted his affair with Nagyova and divorced his first wife.
