The Spanish Congress on Tuesday returned to full activity with a debate which saw it back the plans for the third bailout of Greece.

In the debate, which is not necessary for approving the bailout, Economy Minister Luis de Guindos explained the posture of the Popular Party government of Mariano Rajoy, which will contribute 10 billion euros (around 11 billion US dollars) as part of the agreement.

De Guindos in his speech criticized Greek Prime Minister Alexis Tsipras and his Syriza Party, saying that populist movements were not the solution to economic problems.

People should avoid the "siren calls" and the "false hopes," said the minister.

This prompted speakers from other parties in Congress to accuse that the debate was purely a matter of electoral propaganda, which allowed the government to indirectly attack Spanish populist parties Podemos and Ciudadans, who have recently threatened the two-party system in Spain.

While the Spanish Socialist Party (PSOE) also voted in favor of the bailout, the party's Economic Spokesperson, Juan Moscoso, explained that although it "avoided the breakup of the Euro, we cannot agree with all of its points."
