I thank the hon. Gentleman for giving way again. What he describes requires a really significant change in mindset in the civil service, and particularly in the Treasury, regarding procurement guidelines: they relentlessly refuse to take into account the impact on the prosperity agenda, which they talk about, or even how much they will get in as revenue from the taxes of people working in this country, rather than working in other countries. That goes across the board. Is not it time for a fundamental rethink, in line with how every one of our major international industrial competitors operates?
