Polish investigators ask to question 15 in Czech Republic over oil group purchase

Polish prosecutors investigating the purchase of the Czech Unipetrol oil group by Poland's PKN Orlen have asked for permission to question 15 people in the Czech Republic, a spokesperson for the Krakow state attorney's office said on Friday. Unofficial sources suggest the 15 include the Czech minister of finance, Bohuslav Sobotka, and former prime minister Stanislav Gross. The new management of PKN Orlen says it has uncovered evidence of secret payoffs to Czech politicians.
