Eleven parties are be running, including Junts per Catalunya (Together for Catalonia), led by the former president of the regional government Carles Puigdemont; its former ally, the left-wing ERC; liberal Ciutadans; the Catalan Socialist Pary; and the Popular Party of Spanish prime minister Mariano Rajoy.

Puigdemont is currently in Belgium with four former members of his cabinet, campaigning for elections and after a Belgian court ended an extradition procedure against him.

Four Catalan activist are in jail - including the former government's vice president Oriol Junqueras - waiting for a verdict and with a pending charge for rebellion, sedition and misuse of public funds.

Recent polls show that separatist parties will narrowly fail to secure a majority in the regional parliament, while the turnout could reach a record 82 percent

Brexit

Energy and Transport

On Monday, EU transport ministers will discuss issues linked to renewables and energy union governance.

DIscussions are linked to the "clean energy for all Europeans package", a financial option that will shape European energy policy in the next years and concerns also financing renewable energy projects.

On Wednesday, the Court of Justice of the European Union will decide on how to classify the American transport company Uber, after its top lawyer said in an opinion to the court that Uber must be classified as a 'service in the field of transport'."

The app's features mean that "Uber cannot be regarded as a mere intermediary between drivers and passengers", and that it "is not governed by the principle of the freedom to provide services in the context of 'information society services'".

The final ruling will have repercussions for the so-called sharing economy.
