I am grateful to my hon. Friend for recognising the steps that we have taken, such as on microbeads. As for her main point, we are closely involved in negotiations to develop a UN treaty on marine biological diversity in areas beyond national jurisdictions. As chair of the Commonwealth for the next two years, we will work with member states to create a Commonwealth blue charter. In the G7, we are working closely with Canada during its presidency to deliver our shared ambition to tackle the threats facing our oceans.
