The PSOE would obtain 32.2 percent of the votes according to the CIS survey published this morning on the last day that polls can be published before the elections next Sunday.

The public institute is the only one of the many surveys that have been published that maintains the socialist party above the conservatives.

According to this poll, the PP is in second place with 30.8 percent of the votes, more than one point above the forecast published by the CIS last week.

To sum up, the political project led by Yolanda Díaz ranks as the third political force with a slightly lower percentage than that granted in the last sample, 14.9% of the valid vote. In fourth place is Vox with an 11.8% expectation, one tenth more.

Regarding the peripheral forces, in Catalonia, ERC has added a few tenths and Junts is also rebounding. In any case, the candidacy led by Rufián continues ahead of the list led by Míriam Nogueras.

In the Basque Country the struggle between PNV and Bildu continues where it was, in a draw between both formations, with an identical 1.1%

Last week we learned that for July 23 a total of 2.6 million citizens asked to vote by mail, a record number in Spain.

According to the CIS, PP voters are the ones who have requested the most vote by mail -29.7% of those who have chosen to cast their vote by mail-, followed by followers of the PSOE, who amount to 28%.

If the last CIS showed that 13.8% of the voters had not yet decided their vote, six days before the elections there are still 12.5% ??undecided who will decide their votes during this last week of the campaign.

Among those undecided who have already voted by mail, 53% have had doubts between voting for Sumar or PSOE, while 10.9% of the doubtful have done so between PP and Vox.

Regarding the preference of voters as Prime Minister, the CIS indicates that those surveyed continue to choose to keep Pedro Sánchez in Moncloa. The PSOE candidate leads the preference with 30.7%, the same as in the last poll.

The president of the PP, Alberto Núñez Feijóo, remains almost two points away from Sánchez (28%). The Minister of Labor and Sumar candidate, Yolanda Díaz, is placed in third place again, but she has gone from having a 17.3% preference to 14.6%. Without news, the Vox leader is in last place with 7.2%.

Since January, the survey carried out by the CIS has kept Pedro Sánchez leading the preference among political leaders to be the Prime Minister. In recent months, the leader of the PSOE has found himself in a continuous advantage with numbers that did not decrease from 20.7% (amount obtained in May). Each month his preference index showed a difference of between two and three percentage points, up to 30.7% in the current poll.

In the case of Feijóo, the popular candidate has remained in second place all this time with a distance that did not exceed seven percentage points with respect to Sánchez in any month. For the PP leader, the percentages obtained since January have not decreased or increased much either. In January the study indicated that Feijóo had 16.4% of the preference and in February this amount changed by one point (17.2%). The latest CIS barometer has once again placed Feijóo in second place, but his preference index has increased eight percentage points since the study carried out in June (20.1%).
