The 2017 Northern Ireland Assembly election was held on Thursday, 2 March 2017. The election was held to elect members (MLAs) following the resignation of deputy First Minister Martin McGuinness in protest over the Renewable Heat Incentive scandal. McGuinness' position was not filled, and thus by law his resignation triggered an election. It was the sixth election since the Assembly was re-established in 1998, and the first to implement a reduction in size to 90 MLAs (versus the previous 108).
