In the Guardian yesterday:

The criminal justice system [in England & Wales] is putting more people at risk by failing to tackle potential serial rapists, the victims’ commissioner has warned. Dame Vera Baird expressed the concerns as official figures showed that reports of rape are rising but the number of charges being brought has fallen. Rapes reported to police rose by almost 13,000 to 54,045 in 2017-18, compared with 41,186 the previous year, with 11,913 attacks not recorded as crimes, up from 8,624. The overall charge rate fell from 6.8% to 4.2%, according to data recorded by public bodies, gathered by the Rape Monitoring Group and published by HM Inspectorate of Constabulary.

These figures contrast sharply with the equivalents in Scotland:

Scotland 10% has of the population but less than 5% of the reported rapes. It has 11.4% of those prosecuted compared to only 4.2% in England.
