Available data from the Home Office’s Homicide Index relate to offences currently recorded as homicides in England and Wales as at 4 November 2008. Latest analysis was published in “Homicides, Firearm Offences and Intimate Violence 2007/08” (Home Office Statistical Bulletin 02/09), which is available on the Home Office RDS website.
Between 1998-99 and 2007-08, there were 546 currently recorded homicides where the victim's relationship to principal suspect was ‘current or ex-partner’ and the principal suspect was sentenced to life imprisonment having been convicted of murder, section 2 manslaughter or other manslaughter. This figure excludes those persons for whom a Restriction Order (Mental Health Act 1983 s41) was imposed by the court, since the sentence is without limit of time, and those for whom a Hospital Order (Mental Health Act 1983 s37(1)) was imposed.
