Senior Defense Minister Lord Bach told unions and MPs yesterday that a vital clause would be put on all future defense contracts guaranteeing that all sub contracting work will be done in the U.K. The move came after unions provided irrefutable evidence proving that Swan Hunters had blown a hole in the Government's promise that all warships would be built on the U.K. when, in fact, design and fabricated bow units for the Auxiliary Landing Ships was sent to Holland risking hundreds of jobs in Scotland. Unions belonging to the Confederation of Shipbuilding and Engineer Unions meeting in Glasgow today will demand that BAE Systems on the Clyde retain a design capacity guaranteeing 3000 jobs remaining at the two yards have a long term future.
