He competed against fellow party members Carmen Andrés, Jordi Martí, Laia Bonet and Rocío Martínez-Sampere. Taking place in Ciudad Condal on 29 March 2014, the primary saw a first round in which Collboni and Andrés were the most voted candidates, who subsequently went forward to a run-off. In both rounds, Jaume Collboni was the most voted candidate.^[5]

On 17 June 2023, following the May 2023 municipal election, an absolute majority (23 out of 41 councillors) of the constituent plenary of the new municipal corporation invested Collboni as Mayor of Barcelona.^[6] In his speech after being elected, he proclaimed the three pillars of the incoming government to be economic promotion of the city and jobs, public services and loyalty to Catalan, Spanish and European institutions, otherwise underscoring housing as the "main challenge" of the city.^[7]
