Anti-EU British politician Nigel Farage is to address supporters of US Republican presidential candidate Donald Trump at a campaign rally in Mississippi.
Mr Farage, the former United Kingdom Independence Party (UKIP) leader will appear before 15,000 activists in the city of Jackson.
It was unclear whether he would share the stage with the Republican presidential nominee.
Mr Farage, one of the most ardent campaigners in favour of the British exit from the EU, told local radio in the state the similarities between Brexit and the US election were "uncanny".
He said it was a case of David and Goliath.
Mr Trump, who is trailing his Democratic rival Hillary Clinton in the opinion polls, had also backed Brexit. He saw the blow to British and EU political elites as a good omen for his hope anti-establishment fervour would send him to the White House in November.
Mr Farage's future is unclear. He stepped down from the UK Independence Party after the Brexit referendum delivered what he said was the main ambition of his 25-year political career.
Often seen as an abrasive and controversial figure, Farage was marginalised by the official Vote Leave campaign, which deemed him too divisive. He instead toured the country in a UKIP-purple double-decker bus.
