No, I did not mean prime minister.

In Spain, the head of state is the monarch and the head of the elected government is known as the "Presidente del Gobierno", or president of the government. Although a counterpart can be found in other parliamentarian systems such as the prime minister in the UK, the Spanish president of government is not primus inter pares but the undisputed head of the government.

For those not getting in which context could be a confusion between the words president and prime minister, here's a wikipedia entry[1]
