The Department of Economic Development is defending its figures on the money made for the Isle of Man by the TT.
On Tuesday it was announced £19 million was brought in by visitors to the 2010 event, at an average spend of around £620 per person.
The department's political member with responsibility for tourism Geoff Corkish, MHK, accepts that the figure includes people's travel costs, the money from which goes to the off-Island owners of the transport companies.
However, he says the TT helps sustain services for the Manx public for the rest of the year:
Three-week road closure for gas main works
Public expectations for high street services 'a contradiction'
Info Commissioner partially upholds terminal complaint
MGP organisers ACU respond to accusations of 'hollow promises' following rider's death
