BARROW'S former MP has spoken on the potential detrimental impact Scotland leaving the UK could have on the shipyard. Lord Walney has written in The House Magazine, a leading publication for MPs and Peers, speaking of how if the Scottish National Party get their way and succeed in getting an independent Scotland, it would be detrimental to defence on both sides of the border, and Barrow shipyard. The issue stems from SNP's no nuclear weapons policy which would mean a new location for the Royal Navy's fleet of Trident missile-carrying submarines that dock at Faslane. Barrow is often touted as an alternative in the commons, but Lord Walney explains a hugely costly dredging would be required in the port before any subs could make it their permanent home.
