There's nothing on the Green Party because they're so irrelevant nobody even counts them.
Of the entire population surveyed, the total percentage of people that considered Gaza to be their highest priority was 2%, and of those 2%, the most were in the 18-24 age bracket at 14%.
Admittedly I may be reading that data wrong, and it is from 2024, but this is more current, and on that list, Israel vs Palestine isn't even counted because it's so low in priority. While yes, Israel is unpopular, in the grand scheme of things and the issues facing the UK right now, nobody gives a shit about Gaza.
