I understand that there are about 2,600 last war shelters left in the City of Aberdeen. Normally the removal of shelters at public expense is authorised only if they are structurally unsound, a danger to health or impeding approved development. However, in connection with the scheme for additional capital investment in development districts during this winter, my right hon. Friend has authorised the town council to remove before 31st March next some 500 shelters which do not come within any of these categories and whose potential value for civil defence is negligible.
