MADRID (Sputnik) — British nationals are voting in the referendum to determine whether or not the United Kingdom should leave the European Union. Polling stations across the country stay open from 7:00 a.m. (06:00 GMT) through 10:00 p.m. (21:00 GMT) local time. There is no threshold for turnout, and there will be no exit polls.
Spain's Acting Prime Minister Mariano Rajoy has labeled possible Brexit the worst news for all Europeans, including Spaniards. Almost all Spanish parties and politicians have supported the idea of the United Kingdom maintaining EU membership.
According to a survey by the Ipsos Mori for the Evening Standard newspaper, 52 percent of UK nationals are voting for the country to remain within the European Union. A Populus poll put the number of Remain supporters at 55 percent.
