Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what estimate his Department made of the cost to the public purse of (a) support, (b) infrastructure and (c) training costs prior to the procurement of (i) P-8 Poseidon and (ii) E-7 Wedgetail.

It is taking longer than expected to gather the information needed to answer the hon. Member's question, and I will write to him shortly.
