A major shake-up within the majority NDP government in Nova Scotia. Premier Darrell Dexter has shuffled his cabinet, appointing Maureen MacDonald as the province's first female finance minister. MacDonald takes over for Graham Steele, who announced on Wednesday that he will not seek re-election after an 11-year career in politics. Steele made his announcement during a speech to the Bridgewater and Area Chamber of Commerce. Meanwhile, Bill Estabrooks also announced he will not run again after 14 years in public life, and his former job as transportation minister will be filled by NDP backbencher Maurice Smith. Dave Wilson will become the new health minister, and Leonard Preyra enters cabinet for the first time in Wilson's former job as communities, culture and heritage minister. Steele was first elected to the provincial legislature in a 2001 and sworn in as finance minister when Nova Scotia elected its first NDP government in June 2009.
