MPSP20 was the model parliament session held on the 13th and 14th of January, 2020.
Although the Rat Party won the plurality of seats (127), the most in Model Parliament history, a confidence and supply agreement between the FAM Party (100 seats) and the smaller Plastics (19 seats) and Cyborg (10 seats) parties led to the FAM Party being invited to form government.
Trevor Stewart and his FAM Party cabinet were sworn in a day before the session began. By mid-afternoon on the first day, Trevor Stewart had resigned as Prime Minister, replaced by Kyra Mullen. The government's bill was defeated soon after, and the Rat Party, led by Carolina Munoz was invited to form government. Notably, both opposition motions, from the Rat Party and Plastics were passed.
On the morning of the second day, the FAM party had been rebranded as the Under the Sea Party, and formed the official opposition. Carolina Munoz resigned as prime minister shortly before the vote on her government's bill. She was succeeded in the premiership by Zachary Robichaud. The opposition motion from Under the Sea was able to pass, while both the private member's bill introduced by the GOP, and the Rat government's bill were both defeated. Shortly thereafter, Ethan Clow announced the creation of Young M.U.F.F.I.N., a merger of the Zoomer Party of Canada and L.O.V.E.M.U.F.F.I.N. This new party defected fro the defeated Rat government, alongside members from many opposition parties as well. This new party was able to secure a majority government, which held power for the remainder of the model parliament session. The Under the Sea Party had also been supplanted as the official opposition by the Bone Munchers (formerly the Anti-Burlington Front), while the 'Ferda Party remained a fourth party.
