I am glad that the hon. Gentleman says that I am very efficient because that is what we in the Department of Social Security strive to be.

We now know that the Opposition's approach to national insurance would mean a something-for-nothing society. My hon. Friend points to a further interesting fact: although the figures that I gave were 100 per cent. correct, I would estimate that during five years of any Parliament as we see earnings increase perhaps an additional 500,000 people would be swept into this disreputable proposal from the Labour Benches.
