Scottish referendum: Choppy waters for UK defence projects?

On Friday, the Queen will end a week of engagements in Scotland by naming the Royal Navy's latest aircraft carrier, built at Rosyth and shipyards on the River Clyde.

Allan Little considers the prospects for similar defence projects in the future.
