Scientists, artists and some of the world’s biggest companies are carving up the visual spectrum, and claiming certain colours as their own, so who does have a right to use the colours of the rainbow? We explore the ongoing rift over the worlds “blackest black” Vantablack, which was created by engineering firm Surrey Nanosystems, and can only be used by the artist Anish Kapoor. Contemporary British artist Stuart Semple argues that creativity should not be limited by commercial agreements, while Surrey Nanosystems executive Ben Jensen explains that the material is not suitable for general use. Author Kassia St Clair explores the meaning and history of colour, and we hear how interpretations of colour have changed from Julie Irish, an assistant professor specialising in colour, at the College of Design in Iowa. Note: Surrey NanoSystems has clarified their material Vantablack isn’t toxic, as described by one speaker in this programme, but can be an irritant.(Picture of a colour splash via Getty Images).

Will it last and why have stock markets been shrugging off political developments? A slew of companies have cut off all funding to political parties in the wake of Trump-supporting mobs storming Capitol Hill after the President and other Republican politicians claimed the US election had been stolen. The list of firms who’ve halted funding through their political action committees - or PACs as they’re known - is long. JP Morgan Chase, Citigorup, Facebook, Microsoft, American Express, Morgan Stanley, the chemical company Dow, the hotel chain Marriott and the card company Hallmark which went a step further, admonishing their local senators. Manuela Saragosa speaks to Jason Karaian from the New York Times newspaper who says his paper has run an editorial calling on the country to look again at how corporate America funds the country’s politics. Plus Mohamed El Erian tells her why the share markets were unfazed by all of this.

President Trump's ban from various social media raises the question of their regulation. Are they right to ban him, and what are the implications? We ask Nancy Mace, a newly elected Republican representative of South Carolina. Cory Doctorow, blogger, author and activist in favour of liberalising copyright laws, says that Apple and Google can't blame inadequate moderation for their banning of social network Parler on their platforms. And we hear from Professor Shoshana Zuboff, author of a book The age of surveillance capitalism, who thinks the law will bring the beginning of the end of 'Big Tech'. .

China is forcing hundreds of thousands of Uighurs and other minorities into hard, manual labour in the vast cotton fields of its western region of Xinjiang, according to BBC reports. As a result, apparel companies are facing mounting pressure to withdraw from economic ties with the region, and certainly to stop buying cotton from there. Chloe Cranston of UK-based Anti-Slavery International lays out the case for why companies need to avoid Xinjiang. But as we’ll hear from Andrew Morgan of veteran thread supplier Coats, even though the moral imperative is there, the apparel industry is not completely unified in motivation for change. And we’ll hear from two companies, boutique fashion brand Eileen Fisher and global furniture mainstay IKEA, on their efforts to have an ethical supply chain.

When it comes to choosing a career, should you do what you love or learn to love whatever you do? A clip of Professor Scott Galloway of NYU Stern Business School saying "don't follow your passion" recently went viral. He tells us why you're better off finding something you're good at - and getting very good at it. Someone who did just that is Farid Gasanov. Instead of becoming a professional pianist and composer, he chose accountancy. But he now has his own firm and has time to compose pieces, and play them on the piano he has been able to afford.

In the week when a mob stormed the US Congress, Business Weekly examines the enormous task now facing President-elect Joe Biden. How will he unite the country and how will the new balance of power in Congress affect his economic agenda? Mr Biden’s campaign slogan was “Build Back Better” - we’ll ask whether the world will rise to the task of creating more equal societies once the pandemic is over. Nobel Prize winner Sir Angus Deaton says it’s possible. We’ll also get the secret to a good night’s sleep and hear why women are once again allowed to drive Moscow’s subway trains. Business Weekly is presented by Lucy Burton and produced by Matthew Davies.

Elon Musk, the space pioneer and electric car guru, now ranks as one of the world's richest men, thanks to a surge in the value of shares in his company Tesla. In an interview from 2014, he tells the BBC's chief environment correspondent Justin Rowlatt what drives him to take on some of the world's most technologically challenging projects, and how he feels about the wealth he's accumulated over the years.

The Democrats and President-elect Biden have won control of the US Congress after results came in from two elections in Georgia. Raphael Warnock and Jon Ossoff defeated Republican incumbents Kelly Loeffler and David Perdue respectively. Mr Biden will have a much better chance now of pushing through his legislative agenda. We'll hear from former President Obama's top economic adviser Jason Furman, about how this might shape the country's economic future, while Chris Low of FHN Financial in New York gives us Wall Street's reaction. We'll also be joined live by entrepreneur and former economic adviser under President Bush, Pippa Malmgren to discuss the night of violence seen in the country's capitol buildings.

With much of the world going back into stringent lockdowns and people warned away, or even outright banned, from physical stores and malls, some observers are suggesting this might be the moment online retail takes the dominant position. Others, however, say this is just the last of a long line of challenges for high street retail, and they’re not giving up without a fight. We’ll hear from branding consultant and futurist Karinna Nobbs as well as the self-styled “Retail Prophet” Doug Stephens.

Lessons in rethinking the climate emergency from Sierra Leone and the US. We hear from mayor of Freetown Yvonne Aki-Sawyerr on her plans to plant a million trees, and make climate change relevant to the citizens of the rapidly urbanising capital city. Harvard’s Rebecca Henderson argues that capitalism can provide at least part of the solution, and companies need to price in climate damage, making them financially accountable.

The UK has given the green light to the Oxford AstraZeneca Covid19 vaccine. It’s cheaper and easier to store than some of the alternatives - and the hope is that will make it easier to distribute globally. However, there are worries that production capacity and an unwillingness to share intellectual data might mean the poorest in the world won’t get the immunisation. We speak to Anna Marriott of Oxfam. Also on the show we’ll be mulling over the Brexit deal. We get the view from businesses both sides of the Channel about what the future will bring now the UK and EU have a new trade relationship. We also hear from former EU trade commissioner Cecilia Malmstrom who tells us what effect the divorce will have on the rest of the union. As the rest of the world continues to struggle with Covid 19, China is getting back to normal. We hear from Wuhan and Shanghai. Plus, food businesses discuss how they’ve adapted to survive during the pandemic. Business Weekly is presented by Lucy Burton and produced by Clare Williamson.
