The Director of the National Intelligence Centre, officially Secretary of State-Director of the National Intelligence Centre (SED) is the head of the National Intelligence Centre (CNI), the main intelligence agency of Spain. The SED is appointed by the Monarch at the proposal of the Minister of Defense after deliberation by the Council of Ministers.^[1] The director is the main advisor to the prime minister and to the defence minister in matters of intelligence and counterintelligence.

As head of the Spanish intelligence services, the SED is responsible for promoting the agency's actions and coordinating its units to achieve the intelligence objectives set by the central government, ensuring the adequacy of the Centre's activities to these objectives and displaying the representation of that.^[1]

The SED also prepares the CNI budget; appoints and separates staff; establishes the necessary relationships with public and private entities, with the law enforcement agencies and with the civil and military administrations for the proper development of the activities of the Centre and the SED also heads the National Cryptologic Center.^[1] Furthermore, the director is the only official competent of the CNI to authorize its personnel to use firearms.^[2]

The Secretary of State-Director is legally considered as the National Intelligence and Counterintelligence Authority.^[3] The SED is also member of the National Security Council and the National Defense Council.^[4]

The history of Spain has made it difficult for decades for the intelligence services to articulate themselves as a truly useful organ for governments. The first services date back to 1935 during the Second Republic, but the Civil War prevented its development and even during the dictatorship of Francisco Franco, although these services existed, they were too many, without coordination and each one trying to assume a more leading role than the other.

It was not until 1977, after the first democratic elections, that the prime minister Adolfo Suárez decided to unify the Central Documentation Service (SECED), the Information Service of the Presidency of the Government (SIPG) and the Third Information Section (military intelligence) of the Defence High Command giving rise to the Superior Defense Information Center (CESID). To head this agency it was created the position of Director of the Superior Defense Information Center, a position held by both civilian and military personnel.

In 2002 the current position appears with the creation of the National Intelligence Centre, and it is occupied by the previous director of CESID, Jorge Dezcallar de Mazarredo who stayed in office until 2004, being replaced by another civilian, Alberto Saiz Cortés, until 2009 when Army General Félix Sanz Roldán was appointed.^[5] Roldán hold the office for two terms, until in 2019 when he ceased as director after the end of his term and assumed his duties on an interim basis Paz Esteban López , the agency's Secretary-General.^[6] Esteban was confirmed as director in February 2020.^[7]

In the cases of the director's absence, vacancy or illness, the Secretary-General of the National Intelligence Centre will replace him.

The main functions of the Secretary-General are to support and assist the Director of the National Intelligence Centre in the exercise of his or her functions, to establish mechanisms and organization systems of the agency and to determine the necessary actions for its updating and improvement, to direct the operation of the common services of the agency through the corresponding instructions and service orders, to perform the senior leadership of the agency's personnel, to prepare the relationship proposal of jobs and to determine the vacant positions to fill during each year.^[1]
