Saira Khan lost her temper at Matt Hancock on Loose Women on Tuesday.
The Health Secretary was spotted not wearing a face mask when he was in the back of a chauffeur-driven ministerial car on a trip to the Department of Health and Social Care on Monday.
While you can be fined £200 for not wearing a mask in a taxi, chauffeur-driven cars are exempt but you are still advised to wear one.
Despite this, Saira, 50, said politicians should have to wear face masks whenever they are in public after telling the public how important it is to wear them.
Struggling to keep her voice down, Saira said: "I'm a busy mum, I work, I'm trying to get through all of this.
"Sometimes I watch the news and I might see Matt Hancock getting a car and visually think 'It's alright he's not wearing his so i don't need to wear a face mask.'"
In a comment to the show, a spokesperson for Hancock pointed out that it's not a legal requirment.
They said: "There are different rules for chaffeur driven cars to private hire cars and taxis.
"Ministers are advised to wear face coverings but it is not a legal requirement."
The government has also said that face coverings are put into all ministerial cars and ministers are advised to wear them.
Last month, the Prime Minister's spokesman said Government cars were not classified as private hire vehicles "but the PM and ministers will be wearing face coverings in line with the guidance".
But this wasn't good enough for Saira.
She ranted: "My point is wherever you obliged or not, if you want to drum home the message that a face mask is a necessity wear it at all times because you are setting an example to the nation."
