The Comisión Nacional de los Mercados y la Competencia (CNMC), Spain's competition authority, has announced its decision to not approve the proposed increase in monthly fees for fixed line services by Telefónica. This decision is rooted in the authority's commitment to ensuring competitive practices in the telecommunications sector.

CNMC's rejection highlights its role in monitoring market activities to prevent anti-competitive practices that could harm consumers. The authority aims to maintain a balance in the market, ensuring that consumers benefit from fair pricing and service options.

Telefónica's proposal was seen as potentially detrimental to competition, prompting the CNMC to act in the interest of consumers and the overall market health. The authority's decision reflects its ongoing efforts to regulate and oversee the telecommunications industry effectively.
