Albert Rivera Díaz is the only child of Agustín Rivera, member of a working-class family from La Barceloneta,[2] and María Jesús Díaz, who had moved aged 13 from the small town of Cútar in Málaga province to follow in the footsteps of her elder brother, who had opened an electrical appliances shop.

Over the years, most of his maternal family also moved to Catalonia, except for his grandfather Lucas Díaz, who had been the first to emigrate in the 1960s to France and then to Switzerland.

Once he completed his university studies, Rivera began working as a legal counsel at the La Caixa savings bank in 2003.

Launching the Citizen's campaign for the Parliament of Catalonia in 2006, Rivera published a number of leaflets where he posed naked alongside the caption: "We don't care where you were born.

[9] On 11 November 2019, after the large electoral setback suffered by Citizens on the snap general election the day before, losing over 80% of its seats in the Congress and one-third of its seats in the Senate, Rivera resigned from his position as president of the party and left politics entirely to focus on his personal life.

[11][12] His ousting from the firm two years later was surrounded by controversy, with his former associates complaining of his "low productivity" and "poor performance", and describing his incorporation as an "authentic fiasco".
