Recent polling suggests the Democratic candidate has opened up a significant lead over Donald Trump. The Government is currently attempting to negotiate a new trade deal for Britain with the United States.
Writing in the Evening Standard former Chancellor George Osborne argued a Biden administration is likely to priorities ties with the EU over the UK.
He wrote: “Joe Biden is steeped in the progressive politics of the left.
“Conservative nationalists are not his friends.
“If you want a straw that tells you which way the wind is blowing, then look at the tweet this weekend from Obama’s former deputy national security adviser: ‘I’m old enough to remember when Boris Johnson said Obama opposed Brexit because he was Kenyan.’ Ouch.
“None of these features of a Biden administration are insurmountable obstacles for this British Government.
“But when Boris Johnson turns up in Joe Biden’s Rose Garden, he’s going to have to leave behind the tribe that got him there.”
Mr Biden was vice-president under Barack Obama from 2007 to 2017.
He is currently polling 17 percent ahead of Mr Trump according to the latest Opinium/Guardian poll.

“Now she’s thrown in the issue of our food and pharmaceutical drug standards.
“If we’re not at the back of the queue, we’re nowhere near the front.”
Mr Osborne was a key figure in the pro-Remain ‘Britain Stronger in Europe’ campaign ahead of the 2016 referendum.
Ahead of the vote then President Obama was sharply criticised by Brexiteers after claiming Britain would be “at the back of the queue” for a trade deal with the US if it voted to leave the EU.
By contrast Mr Trump was an enthusiastic supporter of Brexit both before and after winning the 2016 presidential election.
He described himself as “Mr Brexit” and formed a close relationship with current Brexit Party leader Nigel Farage.
Mr Trump is also on good terms with Boris Johnson and has described the Prime Minister as his “very good friend”.
In his article Mr Osborne argued Mr Biden is not ideologically sympathetic to Brexit.
He wrote: “He’s a politician — and politicians don’t easily forget their tribes.
“The Brexiteers aren’t in his tribe. If Biden wins, we’re about to find out what that means.”
