§ Mr. Biffen
asked the Chancellor of the Exchequer what is the estimated loss to the revenue of the non-aggregation of married couples' income for Surtax purposes; what representations he has received advocating separate assessment; and if he will make a statement.
§ Mr. Taverne
I am afraid that the information on which to base the desired estimate is not available. I receive representations on this point from time to time; but I have no statement to make.
