Details of over-inflated public sector salaries have filled newspaper columns for years and fuelled anger about rising pay inequality.

Similarly, the public mood darkens when senior public sector staff also walk away with huge redundancy deals.

Pension inequality, however, has not yet attracted nearly the same attention, but it is just as unfair as quango chiefs earning £200,000 a year.

Caveats do apply. Individuals who earn more will inevitably have bigger pensions on account of employee and employer contributions.

It is also the case that higher earners will pay more tax on their payments than somebody who has an annual pension of £15,000.

However, as today’s revelations show, pension inequality is grotesque and necessitates and urgent rethink.

We have identified ten senior public sector figures whose pension benefits were valued at more than £1.5m.

This is not the sum each individual can withdraw, but is the value placed on pension benefits should they wish to leave the scheme.

For instance, former Scottish Enterprise chief executive Lena Wilson has a cash equivalent transfer value on her pension of around £2.4m.

Wilson will enjoy an annual pension of around £80,000 when she is 60 and a lump sum of nearly £230,000. It is hard to imagine the circumstances in which these sums can be justified.

The time may have come to rethink the system of pension tax relief that disproportionately benefits higher earners. Inequality has many manifestations, but it is particularly evident during retirement.
