Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment the Government has made of the effect of congestion on London’s international competitiveness.

Transport in London is devolved to the Mayor of London and is delivered by Transport for London, which manages the Transport for London Road Network ('red routes'), and is responsible for London’s 6,000+ sets of traffic lights. It would therefore be for the Mayor to make any assessment of the effect of congestion on London’s roads, on its international competitiveness.
