This march never happened. The video was made with Google's AI tools.
Based on 2 strong and 0 supporting pieces of evidence.
What we found
The video is filmed from high up and seems to show a vast crowd marching down a street beneath two giant banners, one a Union Jack and one a Palestinian flag, with chanting on the soundtrack. It was shared on Facebook in late September 2026 with the caption 'UK peoples Stand with Palestine free Palestine free Gaza', as if it showed a real march in Britain. Full Fact checked it and found an invisible SynthID watermark in both the pictures and the sound. SynthID is a hidden marker that Google adds to content made with its AI tools. Full Fact also pointed out small flags that vanish and a crowd that seems to glide down the street, with odd shapes at the edges. Full Fact did not find who made it. When a protest video seems huge, check whether news outlets reported a march of that size on that day.
