Spain's Socialists led in a poll published in the daily El Pais on Sunday, but fell short of a majority with its main ally ahead of a general election next month.
The Socialists would win 27.1 percent of the vote, or 122 seats in the 350-seat parliament. Together with far-left ally Podemos they would have 162 seats in parliament.
That is exactly the same number that a coalition of three right-wing parties — People's Party (PP), Ciudadanos and far-right Vox — would have, according to the poll conducted between March 14-19.
