I've lifted this from B&W website. the link is here: http://wearespartacus.org.uk/reversing-from-recovery/
A new report, ‘Reversing from Recovery’, published by the WeareSpartacus campaign group, analyses figures supplied by the DWP and Motability, to discover what effect of the replacement of disability living allowance with personal independence payment will have on the economy.

They estimate that the losses will include:

3,583 jobs in Motability-related industries
£342 million contribution to GDP
£79 million in tax receipts
Up to £324 million contribution to GDP from disabled people’s ability to undertake paid work.

They’d like your help to make sure that every MP, local paper and Motability dealer sees a copy of the report.
