Where for any period the weekly rate of a Category A retirement pension includes an additional pension, for that period the relevant amount shall be deducted from the amount that would otherwise be the increase under subsection (1) above and the pensioner shall be entitled to an increase under that subsection only if there is a balance remaining after that deduction and, if there is such a balance, of an amount equal to it.

In subsection (2) above the “relevant amount” means an amount equal to the additional pension, reduced by the amount of any reduction in the weekly rate of the Category A retirement pension made by virtue of F2section 42 of the Pensions Act.

In this section any reference to an additional pension is a reference to that pension after any increase under section 52(3) below but without any increase under paragraphs 1 and 2 of Schedule 5 to this Act.

In ascertaining for the purposes of subsection (1) above the rate of a pensioner’s F1age addition to long-term incapacity benefit by virtue of regulations under section 30B(7) above, regard shall be had to the rates in force from time to time.

Regulations may provide that subsection (1) above shall have effect as if for the reference to 8 weeks there were substituted a reference to a larger number of weeks specified in the regulations.
