The director of the museum at the site of a Czech village razed by the Nazis has been fired after a historian revealed that a Jewish woman in hiding there had been denounced shortly before the atrocity.

The village of Lidice, 16 miles from Prague, was where senior Nazi and Holocaust architect Reinhard Heydrich was murdered by British-trained resistance fighters.

Hitler then ordered all male villagers killed and all women and children deported.

Ever since, the government has portrayed the villagers as martyrs, but that legacy has recently been sorely tested by Czech historian Vojtěch Kyncl, who said a Jewish woman in hiding there was detained two days before Heydrich’s killing.

The fallout has led to the dismissal of Martina Lehmannová, director of the Lidice memorial, amid accusations that the government is trying to whitewash inconvenient facts to suit its preferred narrative.
