Parliamentary activity

He was a member of the Assembly of the Republic for one incomplete term, during which he presented, among other things:

• A bill that would make prescriptions and diagnostic aids cost the same for patients, whether prescribed by the National Health Service or in private practice. This bill was never discussed because the Assembly of the Republic was dissolved in the meantime, but the Government approved it in a decree-law, albeit only in relation to medicines;
• A bill aimed at raising public awareness of prevention and health promotion through short messages that television channels would be required to broadcast during the day, for a maximum of 5 minutes per day. The Directorate-General for Health would be responsible for drafting these messages. This bill was never discussed.
