The Brits could well ape their Australian cousins! After each term of parliament, a full report of VIP usage is tabled in the Parliament and then published on the parliamentary web-site. The report includes a/c type, date, sectors flown, pax list on each sector, Block hours and "cost". Cost in inverted commas as what's reported is nothing like the true cost of operating such equipment.
The tabling of the information rarely concerns Joe Citizen. From time to time the popular tabloids will have something irrational to say but VIP fleet usage is simply not on the average Joe's radar.
