On 19 October Canadians chose Justin Trudeau to be their new prime minister as Liberals returned to power. A Liberal government will change Canadian politics and be felt on the world stage as Canada ends its participation in the coalition against IS, refocuses military efforts on training local forces and humanitarian efforts, and launches a national inquiry into missing and murdered indigenous women. On 17 October Guinea's president won re-election but the opposition leader is calling for protests against fraud. On 25 October three elections will be held. One is in Côte d'Ivoire, where the incumbent will be seeking a second term to promote stability. The Tanzanian general election on the same day could be controversial, while Poland’s election results will have repercussions beyond Warsaw - from the role Poland will play in Europe’s refugee crisis to David Cameron’s chances of success in renegotiating Britain’s status in the EU before holding an in/out referendum.
