Each person can contribute between €200 and €10,000, with a maximum of €10,000 for each electoral process, according to the PSOE. The Socialist Party leadership aspires to continue increasing its fundraising, in order to cover part of the budget approved by the Federal Committee for the 23-J election campaign, which amounted to €17.6 million.
Sumar, the project headed by Yolanda Díaz, also uses this system, but with a slightly lower annual remuneration than that of the socialists, 3.25 per cent.
