Duties of Customs

My hon. Friend can see the coast of my Bristol North West constituency from across the channel. Does he recognise that the issue involving ports such as Bristol that import and export tens of thousands of cars, wings, landing gears and engines every year is one not just for businesses, but for the entire city, which will be clogged up, as will cities around ports throughout this country? This will be a nightmare for constituents, but it will also create air pollution, as well as ruining business.
