I totally agree with my hon. Friend about the importance of the conference and exhibition industry. I think it is worth about £90 billion to this country. It is of massive importance. It was a very difficult decision to take to pause conferences and exhibitions. We want to get them open as fast as possible. Of course, they have had a lot of support, as I indicated earlier—the £190 billion package is there to help businesses of all kinds—but the best way forward is to get the kind of testing systems that will enable not just conferences and businesses of that kind but all types and even theatres to reopen and get back to normality. That is what we are aiming for.
