DCLUCIE,Respectfully I beg to differ.Mr Quayle's statements are quite clear.
Those figures do include the fact of the increase in costs of safety.

"He said the estimated overspend was 'directly due to extra expenditure arising in respect of extra costs as a result of the coroner's verdict following the tragic accidents of the centenary TT'."

The figures do include the income gained by business during that period. Mr Qualyle said:

"tens of millions of pounds are brought in by motorsport events every year."
