[2] Martínez Castellano reflected in 2019 that when he arrived at the mayor's office, it only had a table with no drawers, an FC Bayern Munich pennant and a red sofa kept for sentimental reasons as Francisco Franco had once sat there.
[4] Days after taking office, Martínez Castellano was able to pass a two-thirds majority with support from the UCD to ask for a loan of 1.528 billion pesetas.
On 11 June 1979, he hosted a meeting of the mayors of the 20 biggest cities, in which Narcís Serra of Barcelona advocated for financial reform to combat a shared debt that was forecast to reach 400 billion pesetas by the end of the year.
Due to this position, Martínez Castellano was expelled from the Socialist Party of the Valencian Country (PSPV), resigned from office, and was replaced by the second name on the PSOE list for the election, Ricard Pérez Casado.
[7] Martínez Castellano returned to politics for the 2007 Valencia City Council election with the Social Democratic Party.
