Nigel Farage jetted in to the Republican National Convention (RNC) in Cleveland, Ohio today to offer Donald Trump's party tips on how he defied the odds to win the EU referendum.

Many Republican strategists are 'looking very closely at what we did and how we did it,' Mr Farage told an event at the RNC, referring to last month's shock vote in the UK for Brexit.

The outgoing Ukip leader won fans as he ironically thanked President Barack Obama for 'helping us to win this referendum' by urging voters to reject Brexit when he visited the UK in April.

He said this was the reason he didn't want to officially endorse either candidate in the US Presidential race, - insisting it was a 'big mistake for foreign politicians to tell people how to vote'.

But his warm comments towards Mr Trump and previously critical assessment of Hilary Clinton has left few guessing where his allegiance lies in the US election.

'I have to say, I wouldn't vote for Hillary if you paid me,' the Brexit champion told delegates at a breakfast event at the Republican National Convention today.

'There is that sense of entitlement,' he said, pleasing the Republican audience.

But Mr Farage admitted that even he 'winces' at some of the controversial comments Mr Trump makes, such as Mr Trump's contentious pledge to ban all Muslims entering the US.

'Some of Donald Trump's comments are pretty out there,' he told the event.

'To say that you would ban all Muslims coming into America... I can see what he's trying to do; he's trying to reach voters who feel frustrated and, perhaps, a little bit scared.

'Occasionally, the style of it, it makes even me wince a little bit,' he added.

When he spoke to an audience at the Republican National Convention last month, Nigel Farage showed off his British passport - a regular prop for him during the EU referendum campaign as he bemoaned the fact that first words on the cover were 'European Union'

Mr Farage joked that Mr Obama's controversial intervention in the EU referendum debate in April had helped his campaign to persuade voters to leave the EU, winning fans in the Republican audience for mocking the President.

'I think it is a big mistake for foreign politicians to tell people how to vote and how to think,' he said.

'I tell you why I say that – Obama came to the United Kingdom during the brexit debate and actually I shall always be eternally grateful to Obama because he came to our country, he was rude to us, he told us what to do and he led to a big Brexit bounce of several points.

'So thank you Obama for helping us to win this referendum,' he added as he beamed with laughter.

Mr Trump was officially named the Republican nomination for US President early this morning as delegates from each state delivered their votes a the convention centre in Cleveland.

Mr Farage ruled out campaigning for Mr Trump but drew comparisons between the appeal for Mr Trump and last month's Brexit vote, telling the audience: 'I think there are a lot of Republican strategists who are looking very closely at what we did and how we did it.

'All I can do is to come and tell my story.'

Giving his opinion on Mr Trump's meteoric rise, the outgoing Ukip leader said: 'I can see the way this guy – this is not full-throated support – makes an argument, causes a storm, then when he gets condemned by everybody, rather than retracting he goes that bit further.

'I've been watching this with great interest. I'm not surprised he got the nomination at all... just maybe he will reach out to those voters.'

But explaining why he is refusing to endorse Mr Trump, Mr Farage said: 'Having criticised President Obama for getting involved in British politics, I am not about to endorse anybody.

'But I do know a lot of people in the Republican Party and I'll be interested to hear what Donald Trump has to say in his big speech.'

Mr Trump will make his keynote speech at the RNC tomorrow evening and will try to unite the bitterly divided Republican party with less than four months until the presidential election.

Mr Farage praised Britain's new Prime Minister for appointing 'the three Brexiteers' Boris Johnson, David Davis and Liam Fox to the most important Brexit Cabinet jobs.

Mr Farage, who announced his resignation as Ukip leader days after winning his long-sought after vote to leave the EU, said Boris Johnson's appointment as Foreign Secretary was 'great' because he would 'make people smile'.

'I didn't want Theresa May to be Prime Minister because she backed the Remain side. She is our Prime Minister, I think she's made one or two inspired appointments.'

On Mr Johnson's surprise appointment as Foreign Secretary, he said: 'It's great. We've got a Foreign Secretary who is going to raise Britain's profile all over the world and at the same time he'll make people smile a bit and that can't be a bad thing in a world where we don't smile enough, perhaps.'
