I thank the hon. Gentleman for his question. The principle is as laid out in the legislation and it should be recognised as wider than might originally have been contemplated, as concerns were raised during the consultation process on the draft legislation about the definition of reasonable disclosure, and the Government responded to those. The definition of reasonable disclosure in the legislation introduced in the Finance Bill has thus been widened to include disclosure in either an income tax self-assessment return or a corporation tax self-assessment return. The effect of that is to enable disclosure by either an individual or an employer to meet the definition of reasonable disclosure.

Disclosure can be made in more than one tax return of the same type and, as I have said, a tax return includes any accompanying accounts, statements or documents and has therefore been widely specified. How that is to apply in a specific context is, of course, a limitlessly varied matter, and limitless ingenuity will doubtless be deployed in showing that it can be applied to whatever the circumstances are, but that is the standard that the legislation lays down.
