I have a question on the motor tax fund as well. It is collected by what was the Department of the Environment and some of it makes up the local government fund and some of it goes to the Central Exchequer. Am I correct in my understanding of how it operates? How is the amount that goes to the Department of Transport, Tourism and Sport determined? How is that decided?
