Chief of metro network resigns

The chief of Prague's flood-damaged metro network, Ladislav Houdek, has resigned. Prague's Transit Authority announced his resignation on Monday without comment. The Metro's safety chief also stepped down on Friday amid an investigation into whether the underground railway was adequately protected during last summer's disaster. According to Prague mayor Pavel Bem, experts have come to the conclusion that the metro was flooded because it was only built to withstand so-called "century floods" - floods which arrive just once a century. However, the city transportation commission has also been questioning whether officials did enough to protect the metro system.
