According to the Legislative Assembly's electoral law, the election campaign for the anticipated regional elections in Madeira will take place between 12 May and 24 May. This follows the President of the Republic Marcelo Rebelo de Sousa’s announcement of the dissolution of the Legislative Assembly of Madeira on Wednesday, 27 March, and the setting of the 26 May as the early regional election day.

After six months after the regional elections on 24 September, which the PSD/CDS-PP alliance won without an absolute majority, Marcelo Rebelo de Sousa has recovered the authority to dissolve the Legislative Assembly of Madeira, a decision which received a favourable opinion, from a majority of voters from the Council of State.

As stated in article 57 of the Electoral Law for the Legislative Assembly of the Autonomous Region of Madeira, "the electoral campaign period begins on the 14 days before the day designated for the election and ends at twenty-four hours on the day before the day set for the election.” The social democrat Miguel Albuquerque, the president of the Regional Government (PSD/CDS-PP), resigned and was named a defendant in a procedure involving allegations of corruption in the archipelago, which set off the political crisis.

The President of the Republic heard from the parties represented in the Madeira parliament, namely BE, PAN, IL, PCP, CDS-PP, Chega, Juntos pelo Povo, PS, and PSD, as well as to the Council of State, on the morning of the 27 March. All the opposition parties - PS, JPP, Chega, PCP, IL, and BE - returned to argue in favour of early elections.
