The dossier unveiled last week by the Tories detailed what the party calls Labour's 'waste and excess', including £564m being spent on external comms and marketing.
'The biggest spin spender was the Home Office, burning through £73m rather than policing the streets,'
the report stated. Other big-spending government comms departments include the Department for Work & Pensions, which spent £55.3m, and the former Department for Innovation, Universities and Skills, which spent £49m.
The findings are based on 2008-09 spending levels, the most recent financial year for which figures are available.
The report also revealed that hiring external and management consultants cost taxpayers £1.6bn a year.
Philip Hammond, the shadow chief secretary to the Treasury, said the figures showed 'an appalling indictment of the scale of waste'.
However, a Labour Party spokesperson described the Tory claims as 'complete nonsense', adding that 'this is a public report that is part of the Government's ambitious efficiency agenda and was published as part of our ongoing efforts to extend the use of collaborative procurement across the public sector'.
