Millions of angry viewers have vowed to stop ‘knocking one out’ to Countdown after the co-presenter Rachael Riley was photographed wearing an anti-Corbyn t-shirt accusing him of being a racist.

The maths expert in mathematical mathematics wore a garment with a picture of Jeremy Corbyn that had the slogan ‘Jeremy Corbyn Is A Racist Endeavour,’ and the image triggered millions of people to pledge an end to their daily routine of sticking on Channel 4 and treating it like a ten-minute freeview.

It is thought that the photoshopped image was ‘an odd choice’ as it originated from an anti-Apartheid protest,  given that he was protesting against it and Apartheid was basically a big ol’ pile of racist shite.

Viewer Dan Wrist said, ‘She’s a disgrace.’

‘I have enjoyed countless five-knuckle conundrums to that show in the past. With a bit of practice, I have now got to the point where I can finish up, clean up and zip up before the ‘da-dum, da-dum, da-de-la-dum, bong.’

‘Not sure what I am going to do now. The Chase is a bit of a tough one on a number of levels.’

There is a growing amount of speculation over the origin of the photoshopped image on her t-shirt, with experts saying that it doesn’t show all of the signs of a regular Jeremy Corbyn shit post.

One said, ‘There are no spelling errors, no black lines at the top or bottom where it has been screen grabbed, no border text showing the creator’s mobile phone network and remaining battery life.’

‘Whoever made this needs to take lessons from the person who stuck Jezza in front of an IRA funeral in a t-shirt with the slogan ‘I Love The IRA’ on it.
