The Metropolitan police service is riddled with deep-seated racism, sexism and homophobia and has failed to change despite numerous official reviews urging it to do so, an official report will say.

The report from Louise Casey, which is due to be published on Tuesday, will excoriate Britain's biggest police force, the Guardian has been told. Senior government and policing figures are aware of its contents, with one describing it as horrible" and another as atrocious". One source with knowledge of the findings said the report would make clear that the Met was in the last-chance saloon".
