He ran 7th in the Podemos list for the 2015 Madrilenian regional election, and became a member of the 10th term of the regional legislature. During the legislative period he has been ascribed to the ""anticapitalista"" faction of the Podemos parliamentary group, although, similarly to Isabel Serra or Beatriz Gimeno, he estranged himself off from the faction at some point of the term. Following his appointment as Senator on 7 February 2019 by the Assembly of Madrid, he joined the Upper House on 19 February. On 11 March 2019 his inclusion in the Isabel Serra-led list to the regional primary election in Podemos (prior to the 2019 Madrilenian regional election) was announced.
