Are US allegations that Huawei is helping Beijing hack US data networks motivated by genuine suspicions or by trade protectionism?

Joe Miller reports from the US where some Americans feel frustrated that their government is restricting them from using the Chinese tech firm's cheap and reliable products. Meanwhile Ed Butler asks Wired journalist Scott Thurm whether the Trump administration's clampdown is just part of the broader trade standoff between the world's two biggest economies.

Plus, Chinese billionaire and artificial intelligence expert Kai-Fu Lee explains why he thinks ultimately China may win the tech arms race with the US over everything from mobile payments to autonomous vehicles.

Digital advertising fraud cost companies an estimated $16bn last year. Often the clicks or downloads generated by the ads they paid for came not from people, but robots.

Alex Hewson, from mobile advertising firm M &C Saatchi, describes the scale of the problem and the tricks some fraudsters use. And Gary Danks, managing director of Machine Advertising explains how his company is tracking fraudulent app downloads.

The gaming of the online advertising system raises an age-old issue in economics - the principal agent problem. Jerry Z Muller, author of The Tyranny of Metrics, explains and also warns of the dangers inherent in setting targets in business and economics.

As Italy's anti-establishment Five Star Movement and anti-immigration Northern League edge closer to a coalition, we ask whether such a eurosceptic government might scupper plans for further EU integration.

Manuela Saragosa is joined by Federico Santi, from Eurasia Group, and Jeremy Cliffe, Berlin bureau chief at The Economist.

Plus, what do business schools teach about the art of negotiation? We hear from Heather McGregor, entrepreneur and Dean of Herriot Watt Business School in Edinburgh.

New data protection rules are due to take effect in the European Union on 25 May, and complying with them is proving to be a headache for businesses throughout the world.

Manuela Saragosa speaks to two small British businesses struggling to meet the requirements of the new General Data Protection Regulation. Jo Bausor of the Henley Festival of music and arts says she has actually benefited from culling back their database of client contacts. But life coach Clare Josa says it is costing her an arm and a leg to audit all her clients' digital data trails.

Meanwhile Wim Remes of data consultants Wire Security explains why the new European rules have led to a flood of enquiries from clients in the US and elsewhere around the globe.

Does Netflix threaten to wipe out the traditional cinema in much the same way that it already annihilated video rentals?

The online streaming service is spending a lot of money on producing original movies, and its refusal to give them a public screening has led to a bust up with the prestigious Cannes Film Festival. But are these arbiters of the art of the silver screen right to fear Netflix's encroachments?

Manuela Saragosa speaks to Hollywood producer Brian Udovich, author Jonathan Taplin and film critic Jason Solomons.

Hormonal contraceptives liberated women around the world, and are now proliferating in Africa too.

Manuela Saragosa talks to endocrinologist Maralyn Druce about how such a tiny pill can have such a transformative effect on our biology and on our societies. And Faustina Fynn-Nyame of the NGO Population Services International explains why an injectable version of the contraceptive is proving to be a hit in Sub-Saharan Africa.

Plus, why is there still no male pill on the market? We ask research head Diana Blithe of the US National Institutes of Health.

Africa has about a million prison inmates, many of them jailed without a fair trial or proper legal representation, often because they cannot afford it.

The African Prisons Project is working to change that, establishing the world's first prison-based legal college and law firm and working primarily with prisoners in Uganda and Kenya. Susan Kigula, who was put on death row for killing her husband, used the project to overturn her conviction and regain her freedom after 16 years behind bars. She tells us her remarkable story, and we also speak to the project's founder Alexander Maclean.

Plus, we hear from Babatunde Ibidapo-Obe, who has launched an app in Nigeria offering free advice and help on legal services.

The economics profession has sought to reinvent itself since the its failure to foresee the 2008 financial crisis.

Manuela Saragosa speaks to two economists: Wendy Carlin discusses her efforts to transform the way economics is taught in universities in order to make it more relevant to the real world; and Mariana Mazzucato explains why she thinks one of the biggest problems is false narratives that have been peddled to policy-makers and the public about how the economy works.

Feminist economists argue that GDP statistics need to start taking account of care-giving and housework if we want to start valuing these things as a society.

For example author Katrine Marcal points out that Adam Smith claimed that the economy was based on self interest, overlooking the fact that his mother cooked his meals for free. Manuela Saragosa speaks to Hannah Peaker of the UK's Women's Equality political party, and professor Joyce Jacobsen of the Wesleyan University in the US.

For most people, a traffic violation simply means a fine. But for poorer people in the US, it could mean being imprisoned. Since the global financial crisis, local and state governments have tried to make up for shortfalls in tax revenue by issuing more, and larger, fines. If you can't afford to pay, you may well end up behind bars, as the BBC's Kim Gittleson reports from South Carolina.

Presenter Ed Butler talks to Robin Steinberg, CEO of the non-profit Bail Project in Los Angeles, which is aimed at helping accused people stay out of jail while they're awaiting trial. And we hear from Lisa Greybill, deputy legal director of the Southern Poverty Law Centre, and North Louisiana defence attorney Eric Johnson, on the pros and cons of working prisoners.

Israeli Prime Minister Benjamin Netanyahu has made fresh allegations against Iran, adding to mounting pressure on the 2015 nuclear deal. What might be the impact on Iran, and for US and European businesses, if the agreement is ultimately scrapped?

We hear from Iran itself and what the threat of fresh sanctions has done to the country's currency, the money in ordinary people's pockets, and their hopes for the future.

But is the average Iranian actually better off since the lifting of sanctions three years ago? Ellie Geranmayeh, from the European Council on Foreign Relations, tells us the promised economic progress hasn't really materialised. One reason is that huge pressure is still being put on firms not to do business with Iran. Californian entrepreneur Honor Gunday, CEO and founder of online money transfer platform Paymentwall, says his firm received a surge of interest from the Islamic Republic after sanctions were lifted, but that he was warned off by US lobby organisations. We speak to one of those, United Against a Nuclear Iran, and its president David Ibsen. Plus, what next for the nuclear deal? UK sanctions lawyer Nigel Kushner and Ellie Geranmayeh tell us we could be in for many months of renegotiations and a possible trans-Atlantic split on the issue.
