Bernie Sanders can beat Hillary Clinton and go all the way to the White House to become the oldest ever US President, his UK-based brother Larry said today.

And if he wins the Democratic nomination, he will beat the Republican candidate 'easily', Larry Sanders predicted.

Bernie, the 74-year-old socialist who sent shockwaves across the United States by beating Mrs Clinton in the vital New Hampshire primary last week, would 'love' to run against the 'obnoxious' Donald Trump, according to his brother.

Bernie Sanders, pictured in Denver, Colorado yesterday, would find it 'easy' to beat the Republican candidate, according to his brother Larry, who lives in the UK

Larry Sanders, the older brother of United States presidential hopeful Bernie Sanders pictured at his home in Oxford, said he finds the prospect of his brother occupying the White House 'mind-boggling'

Larry, 81, moved to the UK nearly half a century ago and works as a social worker in Oxford.

Last week the Green party appointed him as their health spokesman despite failing to win his £500 deposit when he stood for the party at last May's General Election. He finished fifth behind Ukip.

But in an interview today, he said his brother has what it takes to make history by becoming one of the most left-wing presidents in history, a prospect that he still finds 'mind-boggling'.

And he is hoping to help his brother win the presidency by running the Democrats Abroad campaign, which encourages ex-pats living in Britain to sign up to vote in the election.

'Getting the Democratic nomination is the hardest part as he's up against all her support and money,' he told the Sunday People.

Overcoming Hilary Clinton's patronage and money is the hardest part for Bernie Sanders, his brother said, but if he manages to, beating the Republican candidate in the General Election will be 'easy', he predicted

'But he could beat Trump and the other Republicans easily.'

Larry added: 'Bernard has said he would love to run against him.

'He is the most obnoxious Republican of the lot.'

In the interview Larry reveals how he 'started to cry' when his brother phoned him on his birthday last year to reveal his decision to run for presidency.

Giving his prediction on his brother's chances of winning, Larry added: 'He has incredible support amongst the young,' he said.

'I think it's all up in the air with a slight edge to Bernard. Then he could become the most powerful man in the world. It's mind-boggling.'

The gap between Mrs Clinton and Mr Sanders has narrowed in recent weeks and the US Senator from Vermont won the last primary in New Hampshire by a massive 22 per cent margin - his 151,000 votes was the biggest number that has ever been won in the state.

Nevada's caucus is next, and Mr Sanders will face his first test among non-white voters.

Nevada has a 28 percent Latino population, and nearly 9 percent of the state is African-American. Another 8 percent of Nevada's voters are Asian-American.

Prior to his win in New Hampshire, Mrs Clinton was ahead of Sanders by nearly 20 percentage points in Nevada.

She is also in front of him in South Carolina, where 55 percent of the state's Democrats are black, and 35 percent are black women.

Mrs Clinton is running to be the first woman president, but so far, Sanders has kept time with her in that demographic. She barely won women in Iowa and lost young women to the 74-year-old senator. In New Hampshire he beat her in both categories.

Yesterday Mr Sanders was repeatedly pressed to endorse reparations by his own supporters at a 'Black America' community forum.

'I know you’re scared to say ‘black,’ I know you’re scared to say ‘reparations,' panelist Felicia Perry said, before telling him: 'Can you please talk specifically about black people and reparations?'

Bernie Sanders was repeatedly pressed to endorse reparations tonight by his own supporters at a Black America forum in Minneapolis, Minnesota, yesterday

Sanders replied: 'You and I may have a disagreement on this,' but 'it's not just black. This is Latinos. There are areas of America, more rural areas where its whites, OK?'

As he talked about income inequality and poverty in the 'African-American community an audience member interrupted to urge him to use the term 'black.'

'I've said 'black' 50 times. That's the 51st,' Sanders declared.

Sanders does not support reparations for slavery and said tonight at a Neighborhoods Organizing for Change event located in the heart of Minnesota's Native Americans population that he didn't have a magical solution to the problem.

Midway through the event the Democratic presidential candidate was asked about fixing 'historical grievances' in the context of Native Americans.

He said: 'Anybody who studies the history of our country knows that it has been a very rocky history, it has included the abomination of slavery, it has included horrendous attacks on the Native American community.'
