I wholeheartedly support the case that my hon. Friend is making, as well as the recommendations made by the Welsh Affairs Committee, on which I also sat.
It is not only the disparity in the tolls that is so shocking; there is also the disparity in technologies. We have not seen the introduction of free-flow technology or contactless payment. Those of us who use the tolls regularly know, as do businesses, that a wait in the queue often lasts ages. It is only recently that credit card payments were introduced. Does my hon. Friend agree that the disparities in technologies are also causing problems for businesses and customers in south Wales?
