While it's probably advisable just to let Mr Johnson self-destruct at this point, the politician penned an article in The Times on Monday, in which he encouraged Mr Johnson to take part in a televised Sky News debate:
Don't be a coward Boris, man up and show the nation you can cope with the intense scrutiny the most difficult job in the country will involve.
Given Mr Hunt’s less than sparkling record as health secretary, he should perhaps bear in mind that well-trodden idiom concerning stones and glasshouses.
Luckily, palliative care doctor and bestselling author Rachel Clarke was on hand to remind him about his happy days in charge of the NHS.
Those on Twitter thoroughly agreed with the doctor.
Ms Clarke wasn't the only one left questioning the use of language circulating around Mr Hunt on Monday.
He has previously claimed it would be "morally bankrupt" to stop selling arms to the Saudi coalition forces, which the UN has accused of targeting civilians and has killed dozens of civilians at a time using British-made equipment.
On a similar note Hunt was also called out for a tweet he made denouncing Yemen's Houthi rebels as "cowardly", after an attack on a Saudi airport killed a civilian and wounded 21 others.
Previously the Conservative leadership hopeful claimed it would be "morally bankrupt" to stop selling arms to the Saudi coalition forces, which the UN has accused of targeting civilians and has killed dozens of civilians at a time using British-made equipment.
Earlier this month, Mr Hunt pleaded with broadcasters to make more of an effort not to confuse his surname with the rhyming insult popular in Scotland and Australia.
