Commenting on the opening of the Olympic Games on Friday and their potential impact on British business, Longworth said: "The London 2012 Olympics is a fantastic opportunity to showcase the best of Britain and make it clear to visitors and spectators from across the globe that we are ready to trade the world.
"We believe the Olympics will provide a timely confidence boost for businesses, particularly in the retail, hospitality and leisure sectors, and for the UK economy as a whole. The 'feel-good factor' surrounding the Games is especially critical in the wake of the very poor GDP statistics released earlier in the week.
"The relaxation of Sunday trading laws will help many businesses reap the benefits from the influx of tourists. This eight-week period will serve as a useful trial to provide evidence as to whether the relaxation of Sunday trading rules on a permanent basis would provide a boost to the economy in the long term.
"But we cannot be complacent and assume that the Olympics will be positive for all companies. There is a chance that productivity could suffer as a result of congested transport networks, staffing disruptions, plus delays and cancellations to key deliveries. Olympic organisers and government ministers must stay in close contact with business to minimise disruptions, and ensure that the Games are more of a help than a hindrance to the UK economy.
"Finally, we also must ensure that we present the best possible face to our guests, particularly at our airports. We need to be ready to welcome travellers 24 hours a day, 365 days a year, to demonstrate that our doors are truly open to tourism, investment and trade.
"Border delays put our reputation and future prosperity at risk."
