Lord Sugar has amped up his feud with Piers Morgan by accusing him of being on drugs.
The Apprentice host took to Twitter after watching Piers' rant about Dominic Cummings on Good Morning Britain on Monday.
Piers accused Cummings of "destroying lockdown" after he kept his job following his 250 mile drive from London to his parents' house in Durham when his wife had coronavirus symptoms.
And Lord Sugar was shocked by his impassioned rant, saying his rival "did not come up for air".
He tweeted: "I have just watched the start of @gmb. Morgan did not stop ranting for 10 minutes and did not come up for air.
"He must be on drugs he is so hyper.
"@susannareid100 just Hmming every 2 mins."
Mirror Online has contacted Piers' reps for comment.
Prime Minister Boris Johnson has refused to sack Cummings, saying he "followed the instincts of every father".
Cummings has also refused to apologise.
Piers ranted today: "Why don't we call it what it is, Dominic Cummings is a liar.
"He broke the rules we know it, everyone knows it... they're not gonna shut me down, he broke every rule there is to break."
Piers called the entire situation "nonsense" as he remained in office, despite the backlash.
He added: "We didn't all break the rules, the rules were very straight froward."
Piers continued: "Every part of this stinks and there he is back in his work station like nothing happened."
*GMB airs weekdays from 6am on ITV
