The 74-year-old was elected unopposed and will spend four more years at the helm of the Santiago Bernabeu club.
Perez previously spent time as Real president between 2000 and 2006, and was the brain behind the ‘Galacticos’ project which saw the world’s best players including Zinedine Zidane, David Beckham, Ronaldo, Luis Figo, Michael Owen and a host of other stars arrive at the Spanish capital.
Perez returned to the club in 2009 and helped restore Real Madrid as the best club in world football following a dry spell of success on the European stage. Modern day legends Cristiano Ronaldo, Karim Benzema, Eden Hazard and Kaka were all signed by Perez after he returned to the club.
Real Madrid have won five Champions League trophies under the leadership of Perez alone and a host of other trophies.
Confirming the news on the club's official website, Real have said: "On 13 April 2021, in Madrid, at 00:01 hours, at the headquarters of the Real Madrid Club de Futbol Electoral Board, the individuals listed at the beginning meet to discuss and decide on the matters listed below.
