The government’s intervention to save Flybe has highlighted just how bad a tax Air Passenger Duty really is.

From clerical sexual abuse to the Greater Manchester grooming scandal, the last few days have shone a spotlight on a cultural of impunity and malign political correctness in some of our institutions. For things to change, we need real accountability and a system that not only tolerates whistleblowers, but actively encourages them to come forward.

Policy wonks are in agreement: in order to fix the tax system, the Chancellor should scrap Entrepreneurs’ Relief. And reports suggest he's listening. But while it may not encourage the creation of new firms, the measure is unfairly maligned: it helps attract the best talent in a global market, and underpins London's position as Europe's tech capital.
