This was the case of Greece and Spain. Source: own elaboration from elections results web pages and Poll Base (by Mark Pack). The criteria for the distance is: absolute difference from the estimation (without DA/DK) of the % of valid vote to the final results of the 6 main parties. In the cases of Israel , UK and Netherlands the % of votes have been calculated from the seats estimations.
