NOVOVOLYNSK, Ukraine (Reuters) - Ukrainian police are investigating two companies and a factory over a coal deal which some anti-corruption campaigners say epitomises the difficulties of doing business in the east European country.
The sums involved in the deal are small but the Anti-Corruption Action Centre, an independent watchdog, says it illustrates the lack of transparency in Ukrainian business, an issue in a presidential election on Sunday that has cost President Petro Poroshenko support.
