State Earnings-Related Pension Scheme 28. Sir William van Straubenzee asked the Chancellor of the Exchequer if he will estimate the effect on the revenue of the abolition of the state earnings-related pension scheme. Mr. Moore Estimates of the effect on revenue of the abolition of the state earings-related pension scheme would depend on the assumptions made about any consequential changes in the numbers of contributions made to pension schemes, and in their level.
