MADRID (Reuters) - Socialists were seen winning the European Parliament election in Spain, a GAD3 opinion poll for ABC newspaper showed as voting ended on Sunday.
The result largely reflected the big changes in Spain's political landscape seen in last month's national elections, according to the poll carried out May 22-24.
The Socialists were seen winning 18 of the country's 54 seats in the European Parliament, up from 14 in 2014, while the far-right Vox was seen getting its first EU lawmakers, with four to five seats.
The center-right Ciudadanos, a newcomer in 2014 and now one of Spain's' major parties, won eight seats, from two in the previous election, according to GAD3.
The conservative People's Party, badly bruised in last month's election, would see its number of European Parliament seats drop to 11-12 from 16.
Catalan separatist leaders Carles Puigdemont and Oriol Junqueras were both seen winning EU seats, but with question marks on whether they can become EU lawmakers.
Puigdemont lives in self-imposed exile in Belgium and would be arrested over his role in a 2017 independence bid in Catalonia if he sets foot in Spain to carry out formalities to get his EU seat.
Junqueras is in jail during his trial over the independence attempt.
Spaniards were also voting in local and regional elections, whose outcome will be important in negotiations to form the national government.
The Socialists won the general election last month, but did not capture enough seats in parliament to govern on their own.
A Sigma Dos exit poll showed the Socialists leading in the Madrid regional assembly, where they would have a majority together with the anti-austerity Podemos and another far-left party.
Opinion polls showed the result was too close to call in the Madrid and Barcelona municipalities.
