A welder has been left with huge blisters the size of golf balls and unable to walk after coming into contact with "Britain's most dangerous plant".
Nick Sherratt, 53, said the giant hogweed he touched left him in so much pain that "if somebody came with a hacksaw, I would have gladly said please take it off".
Nick said he accidently touched the plant when he slipped off a footpath at Porthjoke Beach in Cornwall leading down to the sands.
