A government-run poll indicates Spain would end up with an equally fragmented parliament if a third national election were held to try to break the country's political deadlock following two inconclusive votes since December.

The much-watched CIS survey released Monday said the conservative Popular Party, in power since 2011 and now running a caretaker government, would win 32.5 percent of the vote, marginally less than the 33 percent it garnered in the June 26 election.

The leading opposition Socialists would win 23.1 percent, up from 22.7 percent, while the far-left Unidos Podemos alliance would stay third place with 19.6 percent, down from 21.1 percent.

The CIS said the poll had a margin of error of 2 percentage points. It said 2, 479 people were quizzed in person from July 1-11.
