I do not think a 0,8% variation is significant. I would appreciate any news of poll reportings abroad since they may be indications of deliberate spin campaigns. Certainly lousy craftmanship.
There was an on-line error last Friday on la Repubblica site that you may be refering to which indicated an 8% gain. It was an error. It is 0,8%.

I am no expert on polls and statistics but have my suspicions on that particular poll. Also, it does not take into account the difference of forces within each coalition, something I mentioned in my comment.
The two polls indicate a slight change as mentioned above. At the same time B continues to say publicly that polls indicate that he is 1,5 % behind the center-left. This is simply false, yet continues to be reported abroad.
