The Daniel Morgan inquiry: corruption and obstruction at the Met | Letters

Readers J Gwynfryn Jones, Bill Bradbury and Tom Challenor are not surprised by the finding of institutional corruption against the Met. Mary Pimm and Nik Wood think it's time for a duty of candour on public bodies

So, an independent inquiry set up to review the murder of the private detective Daniel Morgan has found that the Metropolitan police were institutionally corrupt" and that the Met commissioner held up the inquiry's work (Daniel Morgan murder report: six critical findings in focus, 15 June). Our home secretary has let it be known that she has full confidence in the Met commissioner. Who was it who said that a corrupt government needs a corrupt police force?

The Daniel Morgan inquiry's lack of legal powers to compel evidence was key to allowing the Met to withhold access to the Holmes database. Andy Burnham's proposal for a duty of candour on public bodies is surely necessary when such obstructive conduct is pursued by the current Met commissioner. And it should also apply to police and crime commissioners, including mayors like him and Sadiq Khan, when they stand by their police chiefs so unquestioningly.
