Geneva Motor Show: 'we need to win back trust' VW boss

Volkswagen's boss Matthias Mueller has warned that a deal with US authorities over its emissions scandal could take longer and cost more than expected.

Speaking at the Geneva Motor Show, he told the BBC's Theo Leggett that VW was still in "constructive dialogue" with regulators and hoped the firm would be "judged fairly".

But he said he would not pre-empt the internal inquiry underway by lawyers Jones Day into what management knew about the emissions issues before it was exposed.
