Volkswagen US boss admits emissions failings

Volkswagen says 11 million vehicles worldwide are involved in the scandal that has erupted over its rigging of US car emissions tests.

It said it was setting aside €6.5bn (£4.7bn) to cover costs of the scandal.

VW chief executive Martin Winterkorn issued a fresh apology for the test-rigging, saying he was "endlessly sorry" for the "manipulation".

Earlier, the boss of Volkswagen's US business, Michael Horn, admitted the firm "totally screwed up".
