To ask the Secretary of State for Defence when he expects to place before Parliament proposals for Initial Gate approval for the programme to replace the UK's Trident nuclear weapons system. 
Mr. Bob Ainsworth:
It is not normal for Parliament to be involved in Initial Gate decisions for procurement projects. I do however propose to update Parliament on progress after Initial Gate. The main investment decision point, and the point at which we would issue the main contracts to industry for the construction of the new submarines, is still several years away.
To ask the Secretary of State for Defence how many months and what percentage time each Royal Navy (a) attack submarine, (b) destroyer and (c) aircraft carrier in service spent (i) on operations and (ii) in maintenance in each year since 2006. 
The following figures are approximate because records held centrally do not always distinguish precisely between routine maintenance and other time spent alongside, since the two activities are often intermixed.
