Mock Elections Wiki:2021 Atlantian general election

Background
Prior to the election, the Atlantian Progressives, led by Prime Minister John Marsh, formed a coalition government with the Green Party. The largest opposition party was the National Party, led by Stephen Carmichael. On 27 February 2021 Prime Minister John Marsh announced he was stepping down as Prime Minister after a thyroid cancer diagnosis in November of 2020. After a leadership election in March, Luna Bay MP and Minister for Energy and Climate Action Kathryn Vallance was selected as leader of the Atlantian Progressives.

Campaign
A total of 15 parties registered to contest the election, the Atlantian Progressives, the National Party of Atlantia, the Liberal Union and the Green Party, each nominated candidates in all 136 constituencies. Atlantian Broadcasting Services (ABS) hosted three television leaders' debates: one between the National and Progressive leaders, one between National, Progressives, Liberals, and Greens, and one multi-party debate. The National–Progressive debate was moderated by Calista Mireault, with the multi party debate and Parliamentary parties debate hosted by Jesse Anderson Hutch.

Electoral system
The 136 members of the House of Representatives are elected in single-member constituencies by first-past-the-post voting. Voters must be 18 years and over and be a citizen or permanent resident of Atlantia.

The leader of the party commanding a majority of support in the House of Representatives is called on by the Governor General to form a government as Prime Minister, while the leader of the largest group or coalition not in government becomes the Leader of the Opposition.
