Early results from Britain's European Parliament elections vote indicate that the country's Euoskeptic party is on track to make its biggest-ever win.

The first official results announced Sunday show that votes for the U.K. Independence Party, or UKIP, have gone up 13 percent compared to the last round of European elections in 2009.

That puts it ahead of Britain's more established parties, the ruling Conservatives and the opposition Labour Party.

UKIP, which holds no seats in the British Parliament, has seen its popularity and profile surge in the past months as Britons grow disaffected with the country's main political parties.

UKIP leader Nigel Farage declared that a win for his party will deliver an "earthquake" to British politics.
