Polish populist politician Andrzej Lepper was found dead on Friday, police said, adding that he most likely committed suicide. The body of Lepper, 57, the leader of the Self-Defence Party, was found in a part office. He had been involved in a lengthy sexual assault case before his death. Lepper was deputy prime minister to Jaroslaw Kaczynski in a 2006-2007 coalition. "Police are at the scene ... but all indications are that the politician committed suicide,” a police spokesman told the Polish news agency Pap.
