But while Britons basked in the aftermath of the annual Guy Fawkes celebrations, held on November 5, some people across the pond embarrassingly mistook the spectacle for a party in honour of the new president-elect. Washington-based news website The Hill ran an article with the headline “Fireworks in London, Edinburgh as Biden win celebrated abroad”.
And ABC News tweeted footage of colourful fireworks in the night sky over London, saying the display was witnessed “after Joe Biden was characterised to be the apparent winner of the presidential election”.
Britons were quick to joke about some US media outlets’ apparent lack of knowledge when it comes to Britain’s bonfire night.
Former Conservative MEP Daniel Hannan tweeted: “Shall we tell them? I wanna tell them!”
Jack Blanchard of Politico said: “Are you going to tell them, or shall I?”
Another amused reader wrote: “Lol… obviously it’s all about the USA.”
And a fourth tweeted: “Tell them it was Fireworks left over from Guy Fawkes on November 5.
“Always happens on the weekend before and after.”
Another person said the UK should host local by-elections on July 4 – Independence Day in America – only to “claim the whole of the US is celebrating it”.
“First some of my friends across the pond conflated Brexit with something Trump did to us.
“And now they think our 400-year-old fireworks tradition is to celebrate Trump’s defeat!”
On Saturday evening the UK received the news that Mr Biden was declared winner of the election by several major media outlets.
Congratulations poured in from around the world for the former Democrat vice-president, who served in Barack Obama’s administration from 2009 to 2017.
Boris Johnson said he looked forward to “working closely” with the Biden-Harris team on the UK-US shared priorities “from climate change to trade and security”.
On Sunday Mr Biden started his first full day as president-elect by attending mass at his local church in Wilmington, Delaware, with family members.
After the service, he visited the grave of his late son Beau Biden, who succumbed to brain cancer at the age of 46 in 2015.
Later on Sunday, Mr Biden and his advisers were working on how to address the nation’s coronavirus crisis while reinforcing his intention to bridge America’s gaping political divisions.
Republican Donald Trump, the first incumbent US president to lose a re-election bid in 28 years, gave no indication of conceding as his campaign pressed ahead with legal fights against the outcome.
