Angry protests, technological glitches and a plummet in value marked the first day of El Salvador adopting Bitcoin as legal tender.

The price of Bitcoin on Tuesday crashed to its lowest in nearly a month, falling from $52,000 (£37,730) to under $43,000 at one point.

An opposition politician said the fall caused one of Latin America's poorest countries to lose $3m.

The rollout of bitcoin in El Salvador was far from what President Nayib Bukele would have envisaged when he began his bold experiment.

Platforms such as Apple and Huawei weren't offering the government-backed digital wallet, known as Chivo, and servers had to be pulled offline after they couldn't keep up with user registrations.

But, as the day went on, Chivo began appearing on more platforms and was accepted by the likes of Starbucks and McDonald's.

The government has even given Salvadorans $30 each of Bitcoin to encourage its adoption. It says bitcoin could save the country $400m a year in transaction fees on funds sent from abroad.

However, using data from the World Bank and the government, the BBC calculates this to be closer to $170m.

"We must break the paradigms of the past," President Bukele tweeted. "El Salvador has the right to advance towards the first world."

Ed Hernandez runs a family shop in San Salvador where customers buy essentials like rice, beans and cleaning products. He's well and truly on board.

"During the pandemic, it will be nice not to use physical cash," he told the BBC, adding that it protects him from customers paying with counterfeit notes.

What wasn't good timing for El Salvador though was the tumble Bitcoin took on its first day as legal tender, falling 20% at one point.

"It was a very bad day for President Bukele, his government and his Bitcoin experiment," opposition politician Johnny Wright Sol told the BBC.

"The majority of the population knows very little about cryptocurrencies. What we do know is it's a very volatile market. Today that was surely made manifest."

Mr Wright Sol said Bitcoin was not an apt national currency and was rushed through: "The Bitcoin law was approved in parliament with hardly any debate. It took only about five hours to go through.

"We're not cryptocurrency or Bitcoin haters, but we don't believe that it should be compulsory that businesses should be obligated to accept Bitcoin in payment.

"The state is backing these payments and assuming the risk but at the end of the day us taxpayers are all the state."

Boris Johnson is continuing to rebuild his ministerial team, after conducting a major cabinet reshuffle on Wednesday.

The PM, who is promising to "build back better" from the pandemic, fired Gavin Williamson as education secretary and Robert Buckland as justice secretary.

In his biggest shake-up since entering No 10, he also replaced Dominic Raab with Liz Truss as foreign secretary.

Mr Johnson is now expected to rejig his junior and middle-ranking ministers in a process which could take days.

In early moves on Thursday, Penny Mordaunt left her post as paymaster general at the Cabinet Office to become a minister at the trade department.

And John Whittingdale has confirmed he will be "stepping down" as a data minister at the Department for Digital, Culture, Media and Sport.

The revamp will give the PM an opportunity to reward Conservative MPs elected at the 2019 election with their first jobs in government.

The big winners from the reshuffle include Ms Dorries, who was promoted from junior health minister into her first cabinet-level job as culture secretary.

The Mid Bedfordshire MP is probably best known outside Westminster for her 2012 appearance on ITV's I'm a Celebrity... Get Me Out Of Here.

Ms Truss, who is the Tory party's first female foreign secretary - and only the second woman to hold the role, following Labour's Margaret Beckett - said she was delighted by the appointment and would use the role to "promote a positive, outward vision of global Britain".

Among the changes made on Wednesday:

Robert Buckland's sacking was greeted with some surprise, with a number of Labour MPs tweeting praise for him and senior Conservative Bob Neill - who chairs the Commons justice committee - saying he "deserved better".

In a letter to the prime minister after his dismissal, Mr Buckland called for more investment in the justice system, adding that "years of underfunding" had made it harder for it to recover from the effects of the pandemic.

New Housing, Communities and Local Government Secretary Michael Gove will get the added responsibility of the government's "levelling up" agenda - spreading wealth and opportunity around the country - while continuing to handle demands for another Scottish independence referendum.

The Daily Telegraph reported that Mr Dowden, following his appointment as the Tory party's new co-chairman, had told staff at Conservative Campaign Headquarters to start preparing for a general election which could be in 20 months' time.

After the early traumas of Brexit, then the emergency and horror of the pandemic, the moves represent, they hope, a refreshed team that can get things done.

Whether it's building houses without upsetting the Tory shires, sorting out school exams, pushing through tougher prison sentences, with new faces it's a government that Downing Street hopes will be more able to push reform forward, and make its case.

Nearly two years after the election, it's perhaps the start of Mr Johnson's third act as prime minister.

Mr Johnson continued making changes late into the night on Wednesday as he got the reshuffle of more junior ministers under way, ahead of wider changes on Thursday.

Long-serving Nick Gibb was sacked from his role at the Department for Education, while Caroline Dinenage lost her job as a culture minister, and Luke Hall was fired as a local government minister.

Amanda Milling, who was removed as Conservative Party co-chairwoman, has become a Foreign Office minister.

Julia Lopez has been moved from the Cabinet Office to the Department for Digital, Culture, Media and Sport, while Greg Hands left the Department of International Trade for a new brief as business minister.
