[1] Jara Andréu joined the Unión General de Trabajadores (UGT) trade union in 1973 while it was still proscribed by the Francoist regime, and in 1978 he joined the Spanish Socialist Workers' Party (PSOE).
[1] In September 2009, Jara Andréu was put forward by the provincial leadership of the PSOE and the People's Party (PP) to be the new president of the Caja Granada savings bank from February 2010, as regional laws prohibited incumbent Antonio Claret García from a third term.
[2] Early into his term, the bank fused with Caja Murcia, Caixa Penedès and Sa Nostra to form Banco Mare Nostrum, with him taking one of two vice-presidencies.
[3] In June 2014, Caja Granada was dissolved as a savings bank and reconstituted as a foundation.
[4] In December 2017, with Bankia poised to acquire Banco Mare Nostrum, Jara Andréu resigned.
