For the Health advisor, José María Vergeles, the percentage of 5.9% of the GDP that at present Spain has dedicated to the maintenance of its public health system is insufficient. "All the financial estimations indicate that a percentage below 7% of the GDP would be insufficient financing for the national health system", he stressed. The social pact signed this Friday seeks to guarantee "economic sustainability", therefore the signers have interpreted it as a message with a view to the future negotiation of a new model of autonomous financing.
