PM Boris Johnson talks to Biden in first call since inauguration

UK Prime Minister Boris Johnson has spoken to Joe Biden for the first time since the new US president was inaugurated.

Mr Johnson said on Twitter that he looked forward to "deepening the longstanding alliance" between the UK and the US as they drove a "green and sustainable recovery from Covid-19".

Mr Biden was sworn in as president and Kamala Harris as vice-president in a ceremony in Washington on Wednesday.

The PM said their inauguration was a "step forward" for the US .

A Downing Street spokesman said Mr Johnson "warmly welcomed" the president's decision to rejoin the Paris Agreement on climate change and the World Health Organization - both abandoned by Mr Biden's predecessor, Donald Trump.

"The prime minister praised President Biden's early action on tackling climate change and commitment to reach net zero by 2050," the spokesman said.

The spokesman added that, in building on the two nations' "long history of cooperation in security and defence, the leaders "re-committed to the Nato alliance and our shared values in promoting human rights and protecting democracy".

The two leaders also talked about "the benefits of a potential free trade deal" between the UK and the US, with Mr Johnson reiterating his intention "to resolve existing trade issues as soon as possible".

Mr Johnson and Mr Biden "looked forward to to meeting in person as soon as the circumstances allow" and to working together during the forthcoming G7, G20 and COP26 summits, the spokesman added.

"It's a big moment for us - we have things we want to do together."

Congratulating Mr Biden and Ms Harris - who is the first woman and first black and Asian-American person to serve as vice-president - the PM said earlier that their inauguration was a "step forward" for the US, which had "been through a bumpy period".

Mr Johnson said it was a "big moment" for the UK and the US and their "joint common agenda".

The BBC's political editor, Laura Kuenssberg has said the Biden Presidency "brings some hope to government" because No 10 believes "there is a lot of overlap" between what Mr Biden and Mr Johnson want to do.

The US president has previously said that he does not want a "guarded border" between the Republic of Ireland and Northern Ireland following Brexit, and that any UK-US post-Brexit trade deal had to be "contingent" on respect for the Good Friday Agreement .

The PM and Mr Biden have never met in real life, but the new US president once referred to Mr Johnson as a "physical and emotional clone" of Mr Trump.

After winning the presidential election, Mr Biden phoned Mr Johnson ahead of other European leaders and expressed his desire to strengthen the historic "special relationship" between the two countries .
