The World Bank is asking the Indonesian government to return $4.7m (€3.7m) in loans for road projects after an internal investigation found that a contractor allegedly paid more than $300,000 in kickbacks to government officials.

The graft allegations are the first to hit the World Bank’s projects in Indonesia since it asked for Jakarta to return $10m (€8m, £5m) related to a school textbook corruption scam in 2004.
