March 15
Elections in Castile and León
March 17
The minister has pledged to present this year's budget even without support during the first quarter. Tuesday, March 17th, is the first available date at the cabinet meeting. Other options include March 24th or March 31st, the latter coinciding with Easter.
March 19
European Council meeting to address the war in the Middle East.
March 20
The Catalan Parliament is debating the entire budget. The Republican Left of Catalonia (ERC) is maintaining its veto without a commitment from the Treasury to delegate the collection of personal income tax (IRPF) to the Catalan government. Should the Parliament reject the budget, the Catalan government will have two options: extend the 2023 budget of Pere Aragonès or call early elections.
Plenary session of March 24-26
Possible appearance of the Spanish president, Pedro Sánchez, to explain Spain's position on the Iran war.
Before April
Meeting between Spanish Prime Minister Pedro Sánchez and Basque Premier Imanol Pradales to agree on the transfer of management of Basque airports and the five-year update of the Basque quota. Two key issues for the relationship between the Basque Nationalist Party (PNV) and the Spanish Socialist Workers' Party (PSOE).
April-May
Finance Minister María Jesús Montero is leaving the government to run for office. Pedro Sánchez will have two options: make a surgical reshuffle, as he did with the departure of Minister Pilar Alegría to run in Aragon, or carry out a broader cabinet reshuffle to face the final stretch of the legislature.
April
Start of the regularization of migrants, once the procedures to definitively approve the royal decree agreed between Podemos and the PSOE have been completed.
The effective regularization of migrants is a prerequisite for Podemos to negotiate the delegation of immigration powers in Catalonia, a demand of Junts. Negotiations between the PSOE and Podemos are underway to bridge their differences.
If an agreement is also reached with Junts, one of the most important commitments of Pedro Sánchez's term to Carles Puigdemont's party would be fulfilled.
April 6
The Kitchen case trial begins, concerning the PP's use of the Interior Ministry to extract information from former treasurer Luis Bárcenas.
April 7
The trial of former minister José Luis Ábalos and his former advisor Koldo García begins in the case concerning face masks during the pandemic. The Speaker of the Congress, Francina Armengol, and Minister Ángel Víctor Torres will be among the witnesses.
April 15
First investiture session of Jorge Azcón (PP) in Aragon.
April-June
The CJEU is expected to rule on the amnesty starting on April 14.
The Constitutional Court will rule on the appeal for protection filed by Puigdemont and the other pro-independence leaders. If the ruling is favorable, it would pave the way for the former president's return.
If, as a result of the Constitutional Court's decision, the Supreme Court fully applies the amnesty to all the leaders of the Catalan independence movement, Sánchez would be fulfilling the major commitment of the legislature to the separatists.
The Supreme Court may choose to refer a preliminary question back to the CJEU and further prolong the process.
May 4th
The deadline for María Guardiola to be sworn in as president of Extremadura and Jorge Azcón as president of Aragon has passed. New elections will automatically be called in both autonomous communities if they have not reached an agreement with Vox beforehand.

Trial of Pedro Sánchez's brother for the position created in the Badajoz Provincial Council.
June
Elections in Andalusia. The date has yet to be finalized and must be decided by the president of the regional government and leader of the People's Party (PP), Juanma Moreno Bonilla.
June 28
If there is no agreement between Vox and the PP in Extremadura and Aragon, this would be the date of the repeat elections in both autonomous communities.
