The Premier of the Province of New Brunswick is in hot water and one of this senior official has had to resign after a letter from an opposition politician concerning a constituent with an 18-month licence suspension for drunk driving was released to the media by the Premier's Press Secretary. The Secretary has since resigned and the Ombudsman of the province is investigating under the province's privacy legislation. (See: canadaeast.com - CP Atlantic Regional News.
