Counter-Terrorism Bill

I am grateful to the right hon. Gentleman for giving way. What would happen if—it is not an overwhelmingly likely contingency—he were Home Secretary and after the police had arrested a whole network of terrorists, perhaps after a terrible incident, they said to him that there was simply no way in which they could get through all the evidence, decrypt all the data and so forth, within 28 days? What if they desperately needed more time if they were to bring charges? What would he do in the absence of the powers that the Bill will give the Government?
