Spain's PP party is requesting a fiscal investigation into payments received by former President Zapatero in the 'Plus Ultra case'. The 450,000 euros he reportedly received from Análisis Relevante are said to closely match the 1% premium Julio Martínez expected for securing the airline's rescue.

Sergio Sánchez claims he was the actual author of the 'Análisis Relevante' reports, receiving 18,000 euros over six years, while former Prime Minister Zapatero and his daughters were paid 660,000 euros for the same work.
