Centro de Investigaciones Sociológicas (CIS)

The Centro de Investigaciones Sociológicas (CIS) is a Spanish public research institute that conducts surveys and studies on public opinion and social issues. Currently, the CIS and its director, José Félix Tezanos, are newsworthy due to accusations of electoral manipulation. The Partido Popular (PP) has announced it will file a lawsuit against Tezanos, alleging he is using the CIS to inflate survey results to benefit the Partido Socialista Obrero Español (PSOE), led by Prime Minister Pedro Sánchez. The PP claims this constitutes a violation of electoral laws, specifically articles 69 and 145 of the LOREG, and aims to unduly influence voters. This controversy highlights concerns about the impartiality and objectivity of the CIS under its current leadership, especially given Tezanos's past involvement with the PSOE. The situation underscores the potential for political interference in public institutions and the importance of maintaining the integrity of pre-election polling.
