Thanks to Rob Edwards for an excellent article on the UN nuclear weapons ban treaty (Scotland and Westminster bitterly divided over historic UK anti-nuke deal, News, July 9). To have the second leader on the same subject was an added joy (Historic first steps to free world from nuclear weapons, Editorial, July 9).

There has been a deafening silence from the mainstream media, ignoring the three stages of this wonderful achievement by realistic and peace-loving states, since September 2016. This appalling lack of concern for the survival of humankind and this world must be remedied.
