MADRID, July 15 (Reuters) - Spain's opposition conservative People's Party (PP) is ahead of Prime Minister Pedro Sanchez's ruling Socialists (PSOE) but still short of winning a decisive majority in this month's general election, according to two tracking opinion polls published on Saturday.
To secure an absolute majority of the 350 lower house of parliament seats needed to form a government after the July 23 election, the PP would almost certainly have to ally with the far-right Vox party, opinion polls have shown.
The PP would win more votes than the PSOE and the far-left Sumar party together, the poll found.
Sumar would win 25 seats or 11.4% of the vote while Vox would claim 11.7% of the vote or 29 seats.
Meanwhile, the PP's share of the vote fell slightly according to a tracker poll by 40dB for El Pais, a centre-left newspaper.
