[Mr John Robertson: ... Type 45s ... will defend the two new carriers that we are about to build. My informants in the Royal Navy tell me that four Type 45s are needed to defend a carrier because the Type 45s corner the carrier to cover the area all round it. As we are to have two carriers, it suggests that we will need eight Type 45s to do the job, so will my right hon. Friend tell me what is happening with Nos. 7 and 8? ...]

Dr Julian Lewis: I warmly endorse everything that the hon. Gentleman has said. To set his point in context, would he like to remind the House that there were originally supposed to have been 12 Type 45s in the programme?
