I will have to write with that estimate. There is every way of doing these estimates that one can imagine. That brings me to the amendment tabled by the noble Baroness, Lady Sherlock, and the noble Lord, Lord Browne, which is to review how many women in this cohort are projected to derive a pension
based on their spouse’s record. We have published a paper on derived entitlement, which covers the projected outcomes for people as a result of removing these provisions. As one may expect, individuals reaching pension age in the few years before April 2016 will have similar national insurance records to those reaching pension age in the few years after April 2016. As such, we can assume that the proportion of women in the cohort under question retiring under the current system who benefit from derived entitlement is broadly similar to the proportion of women reaching pension age just after 2016 who may be disadvantaged.
