Estimates have been made. The interests that promote a national lottery have talked of very high figures in terms of job creation. I am sure that it will have that effect. I believe that as a result there will be much greater activity in the arts and in sport, including building projects, and across a range of charities, and in preserving our heritage. I hear what my hon. Friend says about the pools. As I have said, we shall discuss with the companies the arrangements that may be necessary.
