Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what estimate his Department has made of the proportion of economic growth generated as a direct result of immigration in the last five years; and what estimate he has made of the effect of immigration on the rate of economic growth in the next five years.

Analysis undertaken by the independent Migration Advisory Committee in 2012 shows that higher levels of net migration will, all else equal, increase the growth rate of the potential labour supply and therefore the rate of growth of overall GDP.
