I do note briefly, in response to some of the comments opposite that were just expressed now, that the proposed charge is not a tax in the way that we think about a tax; it is a specific levy which is levied to meet very particular costs related to the quarantine requirements created by the person who is engaging in the travel. Levy costs are, in general, set by regulation, so I don't quite think that some of the arguments put forward there do hold too much water.
