The Popular Party would win a general election again with the same percentage of votes as it achieved in July 2023, while the PSOE would lose almost four points and Vox would register the largest growth among the main parties. This is according to the laSexta barometer, prepared by Invymark based on 1,200 surveys conducted in a week marked by judicial investigations affecting the PSOE and the government's circle.
According to the poll, the PP would reach 33.1% of the votes, exactly the same figure it obtained in the last general elections. The PSOE would be at 27.8%, compared to the 31.7% it obtained in 23J. The gap between the two parties would thus go from 1.4 points in the polls to 5.3 points in the survey.
The most relevant change occurs in Vox, which would rise from 12.4% in 2023 to the current 17.6%. Santiago Abascal's party would gain 5.2 points compared to the last general elections and would consolidate itself as the third national force.
At the other end appears Sumar, which would go from 12.3% achieved in 2023 to 5.5% in the barometer. The comparison must be made with caution because Podemos now appears measured separately, with 3.6%, but even adding both spaces, the whole would fall below Sumar's result in the last general elections.
PP maintains 2023 result and widens lead over PSOE
The central data of the barometer is that the PP would not grow compared to the 2023 general elections, but it would widen its lead over the PSOE due to the socialist fall. The popular party would repeat 33.1% of the votes, the same percentage with which Alberto Núñez Feijóo won the last general elections.
The difference lies in the PSOE's performance. Pedro Sánchez obtained 31.7% in 2023, but the laSexta barometer now places him at 27.8%. This is a drop of 3.9 points that widens the gap with the PP to 5.3 points.
The political interpretation is clear: the PP would not need to grow to improve its relative position. It would be enough to maintain its electoral floor while the PSOE loses support in a context marked by the political and judicial wear and tear of recent days.
Vox is the party that grows the most compared to 23J
Vox appears as the main beneficiary of the new electoral picture. Santiago Abascal's party would go from 12.4% of the votes in the 2023 general elections to 17.6% in the laSexta barometer.
The increase is 5.2 points, the largest growth among the main national forces. This advance would allow Vox to reinforce its position as the third force and increase its weight in an eventual right-wing majority.
The data also confirms a trend that is repeated in several recent polls: Vox is regaining ground after the setback suffered in 2023 and is once again positioning itself at levels clearly higher than those of the last general elections.
Sumar plummets and Podemos appears separately
The space to the left of the PSOE registers the biggest setback in the poll. Sumar achieved 12.3% in the 2023 general elections, but the LaSexta barometer now places it at 5.5%.
Podemos appears measured separately with 3.6%. Even so, the sum of both parties would reach 9.1%, more than three points below the combined result that Sumar obtained in the last general elections.
The data points to a fragmentation of the space to the left of the PSOE and complicates the parliamentary recomposition of the progressive bloc. The fall of Sumar, even with Podemos counted separately, reduces the electoral margin of an eventual left-wing majority.
Feijóo also surpasses Sánchez as the preferred president
The barometer does not only measure voting intention. It also asks who respondents prefer as the next President of the Government.
On this issue, Alberto Núñez Feijóo obtains the support of 54.8% of respondents, compared to 44.4% who prefer Pedro Sánchez. The difference between the two is 10.4 points.
The PP leader's advantage also appears when citizens are asked who they believe will win the next elections. 55.7% consider that Feijóo will be the next President of the Government, while 43.9% believe that Sánchez will repeat in La Moncloa.
Feijóo is the best-rated leader, although all fail
The assessment of leaders maintains a usual pattern in Spanish politics: none pass. Feijóo is the best-rated, with a score of 4.18 out of 10.
Pedro Sánchez occupies second place with 3.63. Santiago Abascal obtains 3.21 and Gabriel Rufián remains at 2.80.
Although the scores are low in all cases, Feijóo's relative advantage reinforces the result of the question on presidential preference and on the expectation of electoral victory.
Comparison with the 2023 general elections
The PP remains at 33.1%, the same result it obtained in the general elections of 23J. The PSOE falls from 31.7% to 27.8%, which represents a decrease of 3.9 points.
Vox rises from 12.4% to 17.6%, with an improvement of 5.2 points. Sumar falls from 12.3% to 5.5%, a drop of 6.8 points, although the barometer also measures Podemos separately with 3.6%.
SALF, Alvise Pérez's party, appears with 1.7% of voting intention, with no direct comparison to 2023 because it did not run in those general elections.
The LaSexta barometer was prepared by Invymark based on 1,200 surveys. The measurement corresponds to May 25, 2026, and occurs in a week marked by judicial and political cases affecting the PSOE and the Government.
