1. The threshold is to be doubled from 2% to 4%.
2. The number of Knesset members needed to dismiss a government will be increased from 61 to 70 (of 120).
I would not count a system of government under that second provision as “parliamentary”; I am not sure what it is, ((It has some features of Assembly-Independent, though it is a less drastic “de-parliamentarization” than that agreed in Papua New Guinea.)) or if there is anything comparable anywhere else.
(As for thresholds, we have discussed the theme extensively before.)
