Senior directors of the German carmaker Volkswagen are meeting today to discuss what actions to take after the company was scolded manipulating its diesel car emissions tests. The board will also decide whether the company's chief Martin Winterkorn should be replaced.

Theo Leggett reports.

“Volkswagon has admitted that 11 million cars worldwide use the same engine management software as those which were able to circumvent emissions testing systems in the United States. The company has already set aside 6.5 billion Euros to cover the cost of recalls in efforts to repair its battered reputation. However, it is also facing criminal investigations in the US, and the possibility of very heavy civil fines as well.”

The British chancellor of the Exchequer George Osborne is visiting China's restive western province of Xinjiang. It is the most controversial part of his five-day trip to China. Amnesty International has called Mr. Osborne to press the Chinese to stop, what it calls, the widespread discrimination against the Muslim Uygur population. Mr. Osborne wants the UK to win building contracts in the capital Urumqi. From there, here is John Sudworth.

“The troubled western region beset with serious human rights concerns presents the Chinese authorities with one of their biggest security challenges. Amnesty International says Mr. Osborne's trade mission here risks handing the communist government a propaganda victory. But on the visit to an industrial park in the city of Urumqi, Mr. Osborne told the BBC that he has raised the human rights issues with government officials alongside the wider economic discussion.”
