Turull was born in Parets del Vallès, Spain. With a degree in law, he joined the Nationalist Youth of Catalonia in 1983 and Convergència Democràtica in 1987. He was a councilor in the City Council of Parets del Vallès in 1987–2003, and headed the Convergència i Unió list in the municipal elections of 1991, 1995 and 1999. He was a member of the Diputació de Barcelona in 1991–1996 and general director of the Catalan Institute of Volunteering between 1996–2000. He was the Regional President of CDC del Vallès Oriental in 2000–2004 and president of the CDC regional federation of Barcelona. He has also been an associate professor at the Autonomous University of Barcelona. Deputy in the Catalan Parliament since 2004, in 2010 he became spokesperson for the Convergència i Unió group in the Parliament of Catalonia and in March 2013 he was appointed as group president. He presided the research commission on the Fiscal Pact of the Parliament of Catalonia. After the 2015 elections to the Parliament of Catalonia, he was elected president of the Junts pel Sí coalition. He held the position until July 14, 2017, when President Carles Puigdemont chose him as Councilor for Presidency and Government spokesman. In the 2019 general election, Turull was elected member of the Congress of Deputies for the Province of Barcelona, being sworn in on 20 May 2019, but on 24 May, by a recommendation of the Supreme Court, the Board of the Congress suspended him and other imprisoned Catalan leaders. He also resigned as member of the Catalan Parliament on 18 May 2019.
Imprisonment
On October 27, 2017 after the Parliament of Catalonia proclaimed the Catalan Republic, the Spanish Senate approved the measures proposed by the Spanish executive pursuant to Article 155 of the Spanish Constitution of 1978, including the dismissal of the President of the Generalitat of Catalonia and the entire executive, including Jordi Turull. On November 2, 2017, eight members of the Catalan Government, including Jordi Turull, Oriol Junqueras, Josep Rull, Meritxell Borràs, Carles Mundó, Raül Romeva, Dolors Bassa, Joaquim Forn and ex-minister Santi Vila, gave testimony before the Spanish Audiencia Nacional general court. The prosecutor, Miguel Ángel Carballo, requested unconditional jail for all members of the Catalan Government, including Jordi Turull, which was subsequently decreed by the magistrate, Carmen Lamela. On December 4, Turull was released on bail after his case passed to the Supreme Court. On December 21, Turull was re-elected to the Parliament with the list of Together for Catalonia in new elections. After the failed attempts to propose Carles Puigdemont or Jordi Sànchez for the presidency, on March 21, 2018, Turull was proposed for president. The investiture took place on March 22, 2018, and the parliamentarians rejected Turull's candidacy for President of the Generalitat with 65 votes against, 64 in favor and 4 abstentions. One day later, on March 23, 2018, the magistrate of the Spanish High Court, Tribunal Supremo, Pablo Llarena sent him back to prison, together with the former president of Parliament Carme Forcadell and the ministers Raül Romeva, Josep Rull and Dolors Bassa. Llarena argued for unconditional provisional bail after considering that was a risk of flight and reiteration of the crimes for which they were prosecuted. In July 2018, he was transferred to a prison in Catalonia. Between December 1 and 21 2018, Turull and Jordi Sànchez started a hunger strike in order to 'raise awareness' of unfair treatment by Spain and to denounce that Spanish courts are refusing to process numerous appeals in relation to their cases. On February 1, 2019, he was transferred back to a prison in Madrid, expecting trial that started February the 12th and ended and was remitted to decision on 12 June 2019. On 14 October 2019 he was sentenced to a 12 years of prison term and disqualification for the sedition and misuse of public funds crimes.>
