The circumstances surrounding the 2005 collapse of carmaker MG Rover are to be investigated, the British government confirmed Monday. The Serious Fraud Office (SFO) said in a statement it had been asked to consider whether there should be a criminal investigation following completion of an inquiry into the failure of the MG Rover Group (MGRG) on April 8, 2005, which owed nearly £1.3 billion ($2.09 billion) to creditors.
