RACHEL BROOKING (Labour): Thank you, Madam Speaker. It's been very pleasing today to hear this issue addressed both in question time and then in almost every speech today about the problem we've often had with older legislation not providing for things like bonds and financial instruments when an environment is left degraded. So we know that orphan sites and legacy contamination are issues and, as I said, it's great that everybody across the House agrees that this is a problem.
