In the first vote scheduled on Sunday afternoon, Sanchez needs an absolute majority of 176 members voting in favor of the motion, a remote possibility at this point. However, he is likely to be more successful in a second round of voting set to take place on Tuesday, for which the Socialist leader will only need more votes in favor than against.
Abstention from Catalonia's ERC should secure this.
If confirmed, the PSOE-Podemos coalition would propose corporate tax increases, more worker-friendly labor legislation and policies aimed to fight climate change and promote gender equality.
However, the government would struggle to push through any legislation given its likely razor thin majority.
