The hon. Gentleman makes an incredibly important point. Our nuclear defence industry makes a major contribution to our defence industrial base. It supports more than 30,000 jobs across the United Kingdom, and benefits hundreds of suppliers across more than 350 constituencies. The skills required in this industry, whether in engineering or design, will keep our nation at the cutting edge for years to come. Along with the hon. Gentleman, I pay tribute to all those who are working in the industry and, by their contribution, helping to keep us safe.
