She was a former Member of the European Parliament for the PSOE ("Partido Socialista Obrero Español" or Spanish Socialist Workers' Party), integrated in the Party of European Socialists. In 2007 she gave up her seat and left the PSOE particularly due to disagreement on what she perceived to be the Socialists' drift on individual liberties, ETA.
She founded a new political party, UPyD (Unión, Progreso y Democracia or Union, Progress and Democracy), based on the existing movement of Basque citizens against ETA violence ¡Basta Ya!. In 2008 and 2011, she was elected to the Congress of Deputies (Spain) representing Madrid district. In the Spanish General Elections of 2011, she was re-elected and her party was the fourth most voted party in Spain.
Díez personally advocates for lower public wages. Subsequently and although she is the UPyD spokesperson on five committees, she is only paid for one of them.
On May 24, 2015 she announced she would not seek reelection as spokesperson of UPyD due to the party's poor performance in the regional and municipal elections.
