(a)require a person carrying on or employed in a business to produce any book or document relating to the business, and take copies of it or any entry in it, or
(b)require such a person to produce in a visible and legible documentary form any information so relating which is contained in a computer, and take copies of it,
for the purpose of ascertaining whether such an offence has been committed.
(2)Such an officer may inspect any goods for the purpose of ascertaining whether such an offence has been committed.

(5)The powers of an officer under this paragraph may be exercised by him only at a reasonable hour and on production (if required) of his credentials.
(6)Nothing in this paragraph—
(a)requires a person to produce a document if he would be entitled to refuse to produce it in proceedings in a court on the ground that it is the subject of legal professional privilege or, in Scotland, that it contains a confidential communication made by or to an advocate or a solicitor in that capacity, or
(b)authorises the taking possession of a document which is in the possession of a person who would be so entitled.
