Following the Government statement to commemorate the 50th anniversary of the continuous at sea deterrent (CASD), Philip Dunne welcomes the decision to maintain the deterrent as the ultimate guarantee of safety for our children and grandchildren in an inceasingly unpredictable world. He also commends the decision to reduce our overall stockpile of nuclear warheads and thereby lead the way in showing that the existing stock of nuclear weapons in the world can be reduced.
