NIGEL Farage is to appear at a Donald Trump rally tonight when the outgoing Ukip leader will talk about how the "anti-establishment beat the establishment" to bring about Brexit.

The two politicians will appear at the event in the Mississippi Coliseum, where tickets have reportedly sold for 1,000 US dollars or £755.

Billionaire businessman Mr Trump has dubbed himself "Mr Brexit" on Twitter and during a visit to Scotland following the June 23 poll hailed the referendum outcome as "a great thing...an amazing vote," saying Britons had “taken back their country”.

A former adviser to Mr Farage stressed how the MEP was not endorsing the Republican candidate but said he did see similarities between the groundswell of support for Mr Trump and the vote to leave the EU.

Raheem Kassam, a former adviser to Mr Farage who is in Mississippi, said: "As I understand it, the plan is for him to speak ahead of Trump's speech and basically just to walk the audience through the Brexit campaign and how the anti-establishment beat the establishment.

"He is very keen to stress that this is not an endorsement; he doesn't want to behave like Obama did during the Brexit campaign, he doesn't want to tell Americans how to vote.

"So he is just there as a storyteller from a country which has gone through a similar election recently."

Asked if Mr Farage saw the groundswell of support for Mr Trump as a similar popular revolt to the Brexit vote in the UK, Mr Kassam said: "Yes, sort of a kick back against same old same old."

The US President sparked controversy after he spoke out against Brexit ahead of the referendum, warning that the UK would be at the "back of the queue" in any trade deal with the US if it chose to leave the EU.

Mr Kassam said he did not know if Mr Farage, who flew over to the US on Tuesday, would appear on stage with Mr Trump.

Meantime, Arron Banks, the businessman who backed Leave.EU, which was associated with UKip, tweeted that he would be meeting Mr Trump over dinner and was looking forward to Mr Farage’s speech.
