§ Mr. Hancock
To ask the Secretary of State for Defence what contingency plans exist in respect of submariners in Trident submarines being trapped on the sea bed; if the Royal Navy has the capability to deal with such emergencies without the use of outside agencies; and if he will make a statement. 
§ Mr. Spellar
The UK submarine Rescue Service has the capability to deal with rescue from any submarine without the use of outside agencies. However, every rescue attempt from a submarine trapped on the sea bed, regardless of nationality, has to be evaluated to determine the optimum solution taking into consideration speed/time and distance. This may mean that it is quicker to rescue distressed submariners using the assistance of other nations' submarine rescue assets.
