The BBC is this morning reporting that the Office of Fair Trading is investigating suspected price-fixing of the UK truck market.
The OFT confirmed to the BBC it had launched both criminal and civil investigations into suspected price-fixing by major lorry manufacturers in the UK.
The OFT said it was looking into suspected cartel activity and investigations were at an early stage.
The probes are being carried out under both the Enterprise Act 2002 and the Competition Act 1998.
Proven price-fixing carries big fines for companies and criminal prosecutions against executives.
The OFT told the BBC it has visited the UK offices of Daimler's Mercedes-Benz as part of a broad-ranging investigation into the pricing of trucks.
