(1)A Category A or Category B retirement pension which is payable by virtue of section 33(2) of the principal Act (which enables benefit to be made payable in cases where the first of the relevant contribution conditions is satisfied but the second of them is not) and a widowed mother's allowance which is so payable shall not be increased on account of a child if the pension or allowance contains no basic component in consequence of a failure to satisfy a contribution condition.
(2)Where a person is entitled to unemployment benefit or sickness benefit at a rate determined under section 14(6) of the principal Act (which relates to persons over pensionable age) or to an invalidity pension at a rate determined under section 15(4) of that Act (which also relates to such persons) and the retirement pension by reference to which the rate of the said benefit or invalidity pension is determined—
(a)would have been payable only by virtue of section 33 of that Act (which provides for the payment of reduced benefit in cases where contribution conditions are only partly satisfied); and
(b)would, in consequence of a failure to satisfy a contribution condition, have contained no basic component,
the said benefit or invalidity pension shall not be increased on account of a child.
(3)Where a person—
(a)is entitled to an invalidity pension at a rate determined under the said section 15(4); and

the amount of an increase of that weekly rate under section 45 or section 46 of the principal Act (which relate to increases for wives and for women with the care of children) shall be the same as the amount of the increase which, by virtue of the said section 45 or 46, would have been made in the weekly rate of the retirement pension if that pension had been payable.
