As per Hansard. This is what the Defence Secretary's said:-
"As has been said from the Dispatch Box before, maritime surveillance from conventional aircraft is not currently funded in the programme. That is one of the capability gaps that my predecessor chose to accept, and a risk that we have chosen to manage. A number of different technologies will be available to deal with it as we approach the end of the decade. That is one of the decisions that the armed forces committee will have to make when it considers the prioritisation for the head room in the planned equipment budget."
So a manned MPA before 2020 does looks very unlikely balanced budget or not!
