Multimillionaire Rishi Sunak has confessed he had to be taught how to use a contactless bank card.
The out-of-touch Tory leadership hopeful was pictured in March struggling to buy a can of his beloved Coke at a petrol garage.
A viral clip showed the till worker raising a barcode scanner, but instead of presenting the can, Mr Sunak held up his card to the plastic screen.
Now he’s admitted it was “the most embarrassing thing” that’s happened during his time as Chancellor - and someone had to explain the technology to him afterwards.
An ally of Mr Sunak later insisted it was a joke.
“The most embarrassing thing that's happened to me is I struggled to pay for the petrol in a car that wasn't my own,” he told a Tory leadership hustings in Darlington.
“Right? So I think you all know about that, right?
“And since then someone's taught me how to use that contactless machine.
“And I tell you, it's an amazing modern marvel this technology these days!”
The gaffe happened during a photo opportunity in which he filled up a Kia Rio with his own money to advertise a 5p fuel duty cut.
Since the stunt, petrol pump prices have risen from £1.63 to £1.89 a litre.
Mr Sunak and his non-dom wife Akshata Murty are on the Sunday Times rich list - largely thanks to her £690m stake in Infosys, founded by her father.
Last year Mr Sunak and Ms Murty won permission to build a private swimming pool, gym and tennis court at their Grade II-listed £1.5m manor in North Yorkshire.
The couple applied for a new stone building on a paddock to house a gym, a 12-metre by 5-metre swimming pool, four showers and utilities and storage rooms.
There will also be a “wildlife area” and a 16-metre by 27-metre tennis court. There is no suggestion he will claim any taxpayer cash for the work, which is on his private home not an official government residence.
Despite attending £46,000-a-year Winchester College, Mr Sunak told last night’s hustings: “I wasn’t born like this.
“My parents worked really hard to provide me with all these opportunities. I’m not going to apologise for what they did for me.
“And in fact that’s why I want to do this job, because I want to provide those opportunities for everyone else.”
He added: “I think in our country we judge people not by their bank account, we judge them by their character and their actions.”
