§ Mr. Blunt
To ask the Chancellor of the Exchequer if he will estimate the tax yield to the UK Exchequer of ending the duty-free concession at airports, and on aircraft, on(a) flights to Europe and (b) all flights assuming that with international agreement similar action was taken by other countries. 
§ Dawn Primarolo
It is not possible to predict with any degree of certainty the additional revenue which will result from the abolition of duty-free sales(a) within Europe and (b) internationally. Estimates are sensitive to a whole range of assumptions about the nature of the successor regime and the post-abolition marketing strategies of the duty-free operators.
