German MEP Manfred Weber said Mr Biden’s election win would give the EU an upper hand in Brexit negotiations with London. The European People’s Party leader bragged Mr Biden stepping into the White House would have an “immediate impact” and give the Brussels bloc “positive leverage”, which would be “better for us Europeans”.
Mr Weber told Euronews: “Boris Johnson cannot say to the citizens in Great Britain that he will get an immediate, great trade deal with the Americans.
“Nobody will buy this anymore.
“On the other hand, Biden was always a clear supporter of the Good Friday Agreement, strengthening the Irish position in the talks.
“So, it is creating positive leverage for us as Europeans in the talks with our British friends.”
It comes after Prime Minister Boris Johnson vowed his government will have close ties with the US under President-elect Mr Biden and they have a shared interest in tackling climate change.
Mr Johnson, who was once dubbed ‘Britain Trump’ by President Donald Trump, congratulated Mr Biden on his victory.
He said: “This country has had a good relationship with the White House over the last few years, but it has a good relationship with the White House for many, many years and I have no doubt we will continue to have a very, very strong, and very close relationship with our American friends.
“One thing that is very exciting that you are already seeing from the incoming administration is their willingness to join the UK in the campaign to tackle climate change.”
It comes amid fears the arrival of Mr Trump’s s successor Democrat Mr Biden will alter the dynamic between the two nations.

Mr Trump has been a good ally for Mr Johnson as he seeks to negotiate a trade deal.
But Mr Biden opposes Brexit and has reservations about the Prime Minister, who he once likened to a “physical and emotional clone” of Mr Trump.
Ministers hope talks with the US will continue as scheduled but cannot rule out that the change in administration, which does not happen until the inauguration on January 20, will delay talks.
One key collision course with the new look White House is over the Government’s controversial UK Internal Market Bill (UKIMB), which gives ministers the power to override international law.
Mr Biden, who is proud of his Irish heritage, has been critical of the controversial legislation which seeks to make alterations to issues relating to Northern Ireland in the Withdrawal Agreement with Brussels.
He warned a trade deal with the US is “contingent” on the prevention of the return to a hard border on the island of Ireland and said the peace process cannot “become a casualty of Brexit”.
