Terrorism: Aviation Security

I thank my noble friend for that question. I cannot give him a precise percentage figure, although the implication of his question is that it is considerable, and in that he is absolutely right. In this country we have some big companies that tend to be both defence and security contractors. Underneath and alongside them are myriad small companies, or SMEs, that are indeed the source of much of the innovation and inventive technology and some of the science. In this respect, I should also mention our universities, which, as I think is widely acknowledged, are going to contribute to and underpin the strength of this country in the defence and security technologies. This Government’s policy is greatly to encourage them to grow and to be real contributors to future security, as well as earning a good living for themselves and this country.
