I should like to thank my hon. Friend, who was an excellent Parliamentary Private Secretary in our Department. She is now able to ask questions in the Chamber again. I have already met the WI to talk about this matter, and there are certain things that people can do, such as using fabric conditioner to reduce the amount of microfibres that get released from synthetic clothing. She will be aware that we are considering a number of issues, and that is why we have had a recent call for evidence on the impact of tyres and brakes, which are also a notable source of microfibres in our marine systems.
