US Republican presidential candidate Ron DeSantis has stepped aside ending his presidential campaign tonight.

The US politician stood down on the eve of the New Hampshire primary after his highly anticipated campaign failed to gain traction.

Taking to X, formally Twitter, he posted a video, with the Winston Churchill quote: “Success is not final, failure is not fatal: it is the courage to continue that counts.”

He added: 'We don't have a clear path to victory, accordingly I am today suspending my campaign.

"I'm proud to have delivered on 100 per cent of my promises and I will not stop now.

"It's clear to me that a majority of republican primary voters want to give Donald Trump another chance. They watch his presidency get stymied by relentless resistance and they see democrats using law fair to this day to attack him.

"I've had disagreements with Donald Trump but he is superior to the present incumbent Joe Biden"

This move will come as welcome news to Donald Trump who viewed Ron De Santis as clear competition for the Republican presidency.
