It is quite proper for my hon. Friend to raise these matters, but the Essex police are fully aware of them and were involved in IRA matters earlier this week. It will be of interest to my hon. Friend and the hon. Member for Essex, South-East (Sir B. Braine) to know that I have checked with the Department of Energy and am told that it has warned all the oil and gas industries in the country to take special precautions against further attacks. Warnings have also gone out to other fuel industries to be especially on the alert. I emphasise that that is most important.
