A NEW video which appears to show the impossible has left folk speculating on social media.

Twitter account @mattparaice4 shared a video that appears to be a Sky News broadcast showing Chancellor of the Exchequer Rishi Sunak leaving Downing Street carrying a red folder.

After passing behind a car, however, the folder magically changes to a bright green colour.

Theories range from Sky News editing the footage for nefarious reasons to proof that we live in the matrix.
