Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will publish National Highways most recent litter survey; and if he will make a statement.

In 2021/22 National Highways reported that 60.8% of relevant parts of the Strategic Road Network had no litter, refuse or detritus, or was predominately free of litter, refuse or detritus apart from some small items, per the Code of practice on litter and refuse. This is the most recent data available. This data is indicative of the motorways and major A-roads network over a year.
