Backbench MP's are calling on ministers to refund the VAT currently paid on fuel used by air ambulances services.
The Hexham MP, Guy Opperman, said the Great North Air Ambulance currently pays more than £100,000 on fuel, with VAT at 20% on top.
Under current regulations, the RNLI doesn't have to pay VAT on fuel bills and MP's would like similar arrangements for the air rescue services. But ministers do not have a free hand on this issue as the VAT exemption rules are enforced by EU regulations.
Lobbying by Tyneside based bakers Greggs lead to a government U-turn over VAT on hot pasties. But Newcastle Central MP Chi Onwurah still isn't happy claiming the 'pretzel sellers' of Newcastle are next in line for the VATman.
The Chancellor George Osborne has admitted he can't remember the last time he ate a Greggs pasty. The comment came in a Commons select committee when he was questioned by Bassetlaw Labour MP John Mann. Mr Osborne wants to introduce VAT on hot takeaway food such as pasties and sausage rolls.
