ICTA88/S577A (1A) applies to blackmail expenditure incurred on or after 30 November 1993. It provides that:
Subsection (1A) applies even if the payer is an innocent victim - see BIM43170. But there are territorial limitations - see BIM43165.
The offence of blackmail is created in England and Wales by Section 21 Theft Act 1968. This says it is an offence for anyone to make an unwarranted demand with menaces with a view of gain to himself or with intent to cause loss to another. An ’unwarranted demand' is made unless the person making the demand has reasonable grounds for doing so and the use of menaces is a proper means of reinforcing the demand. Accordingly, money demanded may be properly due but there would still be an offence if improper menaces are used.
There is similar legislation in Northern Ireland and Scotland. In Scotland the corresponding offence is called ’extortion'.
