(1)Subsection (2) applies if—
(a)a warrant committing the defendant to prison or detention is issued for a default in payment of an amount ordered to be paid under a confiscation order in respect of an offence or offences, and
(b)at the time the warrant is issued the defendant is liable to serve a term of custody in respect of the offence (or any of the offences).
(2)In such a case the term of imprisonment or of detention under section 108 of the Sentencing Act (detention of persons aged 18 to 20 for default) to be served in default of payment of the amount does not begin to run until after the term mentioned in subsection (1)(b) above.
(3)The reference in subsection (1)(b) to the term of custody the defendant is liable to serve in respect of the offence (or any of the offences) is a reference to the term of imprisonment, or detention in a young offender institution, which he is liable to serve in respect of the offence (or any of the offences).
(4)For the purposes of subsection (3) consecutive terms and terms which are wholly or partly concurrent must be treated as a single term and the following must be ignored—
(a)any sentence suspended under section 118(1) of the Sentencing Act which has not taken effect at the time the warrant is issued;
(b)in the case of a sentence of imprisonment passed with an order under section 47(1) of the Criminal Law Act 1977 (c. 45) (sentences of imprisonment partly served and partly suspended) any part of the sentence which the defendant has not at that time been required to serve in prison;
(c)any term of imprisonment or detention fixed under section 139(2) of the Sentencing Act (term to be served in default of payment of fine etc) for which a warrant committing the defendant to prison or detention has not been issued at that time.
(5)If the defendant serves a term of imprisonment or detention in default of paying any amount due under a confiscation order, his serving that term does not prevent the confiscation order from continuing to have effect so far as any other method of enforcement is concerned.
