Question to the HM Treasury:

To ask Her Majesty’s Government how many additional part-time workers, by gender, currently earning between £3,000 a year and the current lower earnings limit they estimate would, by virtue of their earnings, fall within the National Insurance system should the lower earnings limit be reduced to £3,000 and at what gross cost to the Exchequer; how many of those additional part-time workers, by gender, earning between £3,000 a year and the lower earnings limit would currently be credited into the National Insurance system; and what, taking into account existing crediting arrangements, would be the net cost of reducing the lower earnings limit to £3,000.

The information is not available.
