§ Sir Nigel Fisherasked the Chancellor of the Exchequer whether he has advised nationalised industries not to purchase 42W but the total increase in the tax yield from widow's pension in 1978–79 as a result of the November uprating is estimated at £3 million. For a full year, assuming no change in personal allowances, no further pension uprating and no change in other income, these figures would rise to about £12,000 and £8 million respectively. It is not possible to estimate the staff cost of collection since in most cases this is dealt with as part of the general autumn pension recoding.
