Simon Rimmer accidentally cuts his thumb live on air

Sunday Brunch star Simon Rimmer accidentally cut his thumb live on air.

The presenter, 57, was grating carrots on the Channel 4 show when the mishap happened.

Rimmer told the YouTube star: “I don’t want to alarm you but I’ve actually just managed to grate my thumb.

“If we have got the standby team for when I faint!” he quipped to Sugg.

Co-host Tim Lovejoy chipped in: “I think you might actually need to put a plaster on that.”

YouTube star Sugg put his head in his hands and joked he was a “bad omen”.

Rimmer, before getting a plaster, continued his food preparation and told viewers: “So what I’m going to do is use spoons for everything now.”

Sugg was crowned star baker on last year’s Celebrity Bake Off, despite cutting his finger.
