The large, bold red text "BACK" against the bright yellow background.

The video features a bright yellow background. Large, bold, red text appears on screen, changing over time. Initially, only the word "BACK" is visible. Then, "LABOUR" appears below it, followed by "STOP REFORM" in a white rectangle with red text. The text is animated with a slight blur effect, giving a sense of movement. The bottom of the screen has smaller, white text.
