I commend my hon. Friend for that question, which is of great importance. As I have said in earlier answers, we are absolutely committed to exploring and developing lithium mining here in the UK. We fully understand the threats, or dangers, to the supply chain.
My hon. Friend will also appreciate that the Faraday battery challenge, which we have mentioned a number of times, is funding research to reduce our dependency on raw mineral supply and make better use of global resources. That obviously will involve looking at how we can reduce and replace critical raw materials.
