David Hanson MP, shadow policing minister, said:
At a time when the government is cutting support from some of the poorest and most vulnerable people in our society such waste is simply unacceptable.
Police budgets are being slashed by 20% and forces are having to lose 15,000 officers by the next election under this government, so it is good news that hard working chief constables have been able to make some savings.
But this report rightly exposes that the government simply doesn't know what it is doing on this issue, with potential savings through national procurement undermined by the Home Secretary's rushed through police reforms.
