The German carmaker Volkswagen (VW) has said it will recall around 11 million cars because of the emissions tests scandal. The company is in big trouble. Some industry experts say the recall could cost the automaker more than $6.5 billion. Last week, VW admitted cheating in emissions tests in the USA and Europe. It changed data to falsely show that VW cars were more fuel-efficient than they really are. VW is Europe's largest carmaker and employs over 750,000 people. It has lost more than a third of its market value and has damaged its image as being a leader in clean energy.

Bosses at VW could face criminal charges. A Volkswagen board member told the BBC that some staff acted criminally over emission tests. He said the people who let this happen, or who decided to install the cheating software, acted criminally. He said they must take responsibility. He added: "We only found out about the problems in the last board meeting, shortly before the media did. I want to be quite open, so we need to find out why the board wasn't informed earlier about the problems when they were known about over a year ago."
