The UK boss of Volkswagen is to face MPs today to answer questions about the diesel emissions scandal.
The German car manufacturing giant admitted 11 million of its vehicles worldwide were fitted with software that cheated environmental tests in the US.
It recently also revealed nearly 1.2 million vehicles are affected in the UK.
The Transport Committee will hear evidence from Paul Willis, Managing Director at Volkswagen Group UK on the scandal and what action the company is taking as a result.
The Society of Motor Manufacturers and Traders (SMMT) will also give evidence on the effect on the wider motor manufacturing sector.
The Vehicle Certification Agency and Transport Secretary Patrick McLoughlin MP will be questioned on what steps the government is taking to restore public confidence in the vehicle type arrival testing regime.
Environmental group Friends of the Earth said the committee must “get to the bottom of this public health scandal by thoroughly grilling VW’s UK chief and Patrick McLoughlin on what they knew about the company’s efforts to cheat emissions tests”.
Last week the US head of Volkswagen admitted he knew about the emissions cheating in spring last year.
