As I said, I will write to my hon. Friend about that, because it is an important point. If there is not proper monitoring, we cannot know what is going on. I want to get to the bottom of policies on grass cutting and other things.
National Highways and the Highways Monitor will report litter performance to the public in their annual reports, providing increased transparency. That happened only in road investment strategy 2. That is the era we are in now—between 2020 and 2025.
As hon. Members know, in 2021-22 National Highways reported that 61% of the network was graded A, which is no litter, or B, which is a small amount of litter. That means that a large proportion of the national highways—39%—has a significant amount. Although that is an improvement on 2020-21, which was about 49%, there is clearly still a lot of work to do. I do not underestimate that. Those grades are alongside DEFRA’s litter code of practice. The data for 2022-23 will be published this summer, so I ask hon. Members to keep an eye out for that.
