He will go on the sex offenders' register and will have to notify the police of his address wherever he moves in the country for seven years.

If the police feel there is an operational need to inform selected local people of the pop star's presence, they will have that right.

The Register of Sexual Offenders was established by the Sex Offenders Act of 1997.

The Act requires anyone convicted or cautioned for specified sex offences to notify the police of their names and addresses and any subsequent changes.

Offenders who do not register within 14 days will be committing a criminal offence and will face penalties of up to six months in prison and/or a £5,000 fine.

The registration is for a minimum period of five years but may be up to life.

The Home Office says the number of people on the register is not kept centrally.
