The threat level in this country is set independently of politicians by the Joint Terrorist Aanalysis Centre and they look at a range of things. I think it’s a perfectly logical way and we do it so politicians can’t interfere with threat levels and manipulate them for any means. It is done entirely at arm’s length of government and that’s why they did it. In this case imminent means that we know there was an attempted attack on a tube yesterday morning, it used the type of explosive similar to that used in Manchester. The sort you can buy with certain ingredients in high street shops although there has been a lot work to now prevent that.
