§ Over the whole field of military and civil preparations for defence, apart from the stockpiling programme, expenditure in the financial year 1951–52 will be in the neighbourhood of £1,300 millions. It will take time to build up defence production to the levels which we now have in mind, and expenditure on production will be on a rising curve during the next three years. If the programme is fully achieved, the total defence budget over the next three years, covering all the military and civil preparations but again excluding stockpiling, may be as much as £4,700 millions. Nearly half of this will be for production. I should once more call attention to the limitations on production which I mentioned earlier, and to the fact that these limitations may make it impossible to spend this sum within that period.
