Britain's outgoing UKIP leader Nigel Farage has appeared alongside Donald Trump to give a speech at a rally in Mississippi.

He spoke about his role in the successful campaign for Britain to leave the European Union, but stopped short of endorsing Mr Trump for president.

He told the crowd: "I come to you from the UK with a message of hope, and a message of optimism."

"It's a message that says if the little people, if the real people, if the ordinary decent people are prepared to stand up and fight for what they believe in, we can overcome the big banks and the multinationals."

He criticised Barack Obama for publicly backing the Remain campaign during the EU referendum campaign, before adding: "So I could not possibly tell you how you should vote in this election."

As the restless crowd started shouting he said: "I get it, I get it, I'm hearing you. I will say this, if I was an American citizen, I wouldn't vote for Hillary Clinton if you paid me."

"In fact I wouldn't vote for Hillary Clinton if she paid me."

"Folks, the message is clear. The parallels are there. There are millions of ordinary Americans who feel let down."

"You have a fantastic opportunity here with this campaign, you can beat the pollsters, you can beat the commentators, you can beat Washington."

Mr Farage repeatedly mentioned that the Leave campaign had beaten the odds.

It was an apparent acknowledgement that Mr Trump's poll numbers have slid in recent weeks, and bookmakers now rank Mrs Clinton as the clear favourite.

Many Trump supporters have voiced nationalist, anti-globalisation, anti-establishment views, which have been echoed among many who voted for Brexit.

Mr Trump caused a stir last week with a cryptic tweet in which he said: "They will soon be calling me MR BREXIT!"

The real estate businessman supported June's UK vote to leave the European Union and described it as "the people taking the country back".

During a visit to his golf resort in Scotland, in the aftermath of the referendum, Mr Trump said the result was a "great thing".
