What makes you think an answer is coming shortly out of interest?
It is my opinion - not shared by everyone on here - that this capability gap will have to be addressed in SDSR 2015. Notwithstanding the potential for political turmoil which could be about to descend upon us, I would imagine that SDSR 2015 will progress in one form or another - maybe with a short delay?
If no allocation for an MPA/MMA/whatever is made in SDSR 2015, I personally think it is game over - but others will disagree and as I wish to see the the return of an MPA force, in one guise or another, as much as anybody, I hope I am being unnecessarily pessimistic.
