The royals bill taxpayers for personal travel because they're "always on duty"
The royals' taste for luxury travel – and the exorbitant costs that go with it – is well known. But many people assume the taxpayer only foots the bill for travel to and from official royal engagements.
In fact, the royals routinely use public funds to pay for private trips. In 2011, for example, Prince Charles charged taxpayers £30,000 for a return flight from Clarence House to Balmoral for a four day break on which no public engagements were undertaken. When asked why Charles didn't pay for his own private travel, Clarence House said that he was "always on duty".
