Liz Truss made an amusing first gaffe just minutes after securing her spot onto the Tory leadership ballot.
The Foreign Secretary's first tweet after she made it onto the ballot with ex-Chancellor Rishi Sunak told Brits she was "ready to hit the ground".
Many observers were quick to point out she may have missed out the word "running" from the popular phrase - changing the meaning entirely in an awkward gaffe.
Earlier this afternoon, Ms Truss managed to beat Trade Minister Penny Mordaunt by just eight votes, tweeting two minutes after it was announced: "Thank you for putting your trust in me. I’m ready to hit the ground from day one."
The tweet was hastily deleted - but not before it was screenshotted by amused Twitter users. She later wrote another to say: "I’m ready to hit the ground running from day one."
In a press release, she also used the correct phrasing.
Some eagle-eyed people on Twitter spotted the gaffe and made their own jokes.
Bestselling author James Felton wrote: "Hit the ground from day one. F***** Donkey Kong for PM.
"Rishi Sunak? Nah mate, looking for a PM who’ll pummel the f*** out of the ground and finally rid us of Mario."
Ms Truss won 113 votes compared to 105 for Ms Mordaunt in a final ballot of MPs. Mr Sunak won 137 votes, easily making his way into the final two.
It means the pair - who clashed bitterly in leadership debates, with Ms Truss saying Mr Sunak’s plans are leading Britain into recession - will tour the country for more than a dozen hustings.
And around 180,000 Tory members will vote between them for the winner who will be announced on September 5. Boris Johnson will resign and his successor will take office at 10 Downing Street on September 6.
Mr Sunak was the frontrunner with MPs - but polls have suggested Ms Truss will be more of a hit with the members.
At his final PMQs, Boris Johnson praised Ms Truss's Foreign Office - and fired a parting shot at ex-Chancellor Mr Sunak, saying big projects would not have been built "if we'd always listened to the Treasury".
The outgoing PM's closest allies are backing Liz Truss, who has promised vast tax cuts if she takes over - but not said fully how they'll be funded.
Allies of Boris Johnson blame Mr Sunak - who was nowhere to be seen at PMQs - for kicking off the slew of resignations from the Government that led to Mr Johnson's departure.
The PM gave some "words of advice" to his successor including: "Cut taxes and deregulate wherever you can and make this the greatest place to live and invest, which it is".
Mr Johnson, who was brutally axed by his own MPs after months of scandal, offered his successor some advice: "Focus on the road ahead, but always remember to check the rear-view mirror".
