Since the municipal corporation began its term in mid-June 2023, a total of six out of the twenty-five councilors who took office have left the plenary hall. This situation has created a sense of instability among the town's political representatives.

The first councilor to resign was a representative of a local party in October 2023, due to internal party disputes. He was replaced by another member of his party. Subsequently, in December 2024, a socialist councilor withdrew from municipal politics for health reasons, being replaced by another party colleague.

In the spring of 2025, a Vox councilor also left his post for professional reasons, and his place was taken by another member of his party. Later, in March 2026, the head of areas such as Family and Social Services in the Collado Villalba City Council was forced to resign and give up her seat after an incident during a satirical monologue.

Recently, two more Vox councilors, who had been acting as non-attached members since February 2026, announced their resignation, which will become effective at the next Plenary Session on Thursday, April 30. This situation could lead to other names from the Vox list from May 2023 joining the City Council.

The town's mayor has acknowledged the complexity of the situation, stating that she had never before faced a similar scenario of party disintegration. She also mentioned that her local party's situation with Vox is unique, although she recognizes that the trend of resignations in this party is occurring in many municipalities in the Community of Madrid and throughout Spain.

This series of resignations has political and economic implications, especially for the Vox municipal group, which regains representatives, and for the Popular Party, which remains in the minority with ten councilors and whose support from Vox remains essential.
