Mr. Ronnie Downes:

It might be helpful to take transport as a case in point. We have invested a great deal over the past decade and more in upgrading our transport infrastructure. To make sure we get continuing value from that, there is an ongoing need for maintenance. That expenditure, in turn, is treated as part of the overall capital envelope. My colleague, Ms Callaghan, may want to come in and give her observations in response to the Chairman's query.
