That is a fair comment. I was referring to the Competition Act 1998, where the phrase
“agreements, decisions or concerted practices” appears. If some legal agreement meant an airport suddenly having a power that it did not previously have, there would be a need to regulate. The hon. Gentleman is right that “circumstances” is so broad that it could mean things that do not yet exist, because it is an advance power. Yet there are no legal documents that actually bring those into force. It is hard to understand exactly what would be regulated in this situation. Will the Minister clarify what “circumstances” means? Might there be a better way of defining when the power can be used?
