In a series of pieces, Manveen Rana has been investigating the relationship between political power in South Africa, a London-based PR firm, and one of the country's richest families. As the President faces a vote of no confidence, what links Jacob Zuma, the Gupta Brothers and Bell Pottinger Public Relations? And, with anger at corruption spilling over from the streets to parliament, has Nelson Mandela's rainbow nation been put in jeopardy by a political campaign born in Britain?

Until recently, South Africa was hailed as one of the so-called BRICS - the developing economies, growing at such a rate of knots, they were soon to join the economic premier league. Not anymore. Next week, President Jacob Zuma faces a vote of no confidence, fuelled by accusations of financial corruption on a gargantuan scale. One of the principal businesses to have been roped into the scandals are the Gupta brothers, a family whose tentacles extend from media-ownership to railways, coalmines and armaments; the common thread being the ownership of formerly state-run companies. The Guptas have been the subject of highly critical media coverage, as well as a report by the South African public protector's office into their links to government ministers, President Zuma himself, and members of his family. The Guptas strenuously deny any suggestion of corrupt behaviour. Indeed, not only have they submitted sworn affidavits to the contrary, but they say the media is in the hands of a 'white monopoly capital', which is hell-bent on tarnishing their name, along with a few old white families who ensure their business is stymied at every turn. In the third of four special reports, Manveen Rana was granted a rare interview with Atul Gupta and discussed, frankly, their reputation. (Photo: Protesters in South Africa. Credit: Getty Images)

It is 23 years since the birth of South Africa's Rainbow Nation and it stands at a watershed. Its President, Jacob Zuma, is facing a vote of no confidence in parliament next week, which could see him kicked out of office in a country increasingly angry at his conspicuous enrichment, while the poorest get poorer. At issue is the President's relationship with one of South Africa's richest families, the Gupta brothers. In the second of her four part investigative series, Manveen Rana, looks into the allegation that the British PR firm, Bell Pottinger, was hired, in part, to inflame racial tensions on behalf of the Guptas, in order to distract from a massive financial scandal at the heart of Government - an allegation that Bell Pottinger deny.

The PR firm Bell Pottinger has often courted controversy with its choice of clients; they represented the Paralympian Oscar Pistorius after he was charged with murder, Asma al-Assad the Syrian first lady, and the Pinochet Foundation, whilst the former Chilean dictator was being detained in Britain. But the latest crisis the company faces could be the most challenging yet - they stand charged of fomenting racial tensions in the tinderbox of post-apartheid South Africa. In his first broadcast interview following the scandal, the CEO of Bell Pottinger is adamant that this was never their intention. Manveen Rana has the first of four special investigative reports across the week. (Photo: Demonstrators protesting against the South African president. Credit: Getty Images)

Despite decades of research, 99% of clinical trials on new drugs for Alzheimer's disease have failed, meaning there is still no cure. But scientists believe it is not the drugs which do not work, it is the trials. To test the theory, work is about to begin on the world's biggest and most in-depth study to find the earliest signs of Alzheimer's in people. Scientists believe that if the drugs were used earlier, before the clinical symptoms of memory loss, they could slow the onset of the disease or even stop it entirely. Andrew Bomford takes a closer look at the research. (Photo: Brain scans. Credit: BBC)

Sir John Major has said he is "wary" and "dubious" about Theresa May striking a deal with the DUP to give her government a majority. The former Conservative prime minister, who was one of the architects of the peace process in Northern Ireland, told the World at One the peace process in Northern Ireland was "fragile" and "under stress" and said there was a danger the UK government wouldn't be seen as impartial if it was "locked into a parliamentary deal at Westminster with one of the Northern Ireland parties". Sir John said he had sympathy with Theresa May trying to shore up her parliamentary position but that she could carry on without a deal, an option he said would be without "baggage".

With polling day less than a week away, heated arguments are bound to be happening in homes around the country. Our election family are used to that. They are the Groves and are from Rowley Regis, near Dudley in the Midlands, and their cousins, the Stevens live nearby. In the third episode of her series, our reporter Becky Milligan has joined the family for a night out playing bingo at the local social club. It's also the first time Becky meets someone she has heard a lot about, Danny. He is Imogen Grove's step-father, she calls him Dad, and he's been Tina's partner for over 20 years.

As a foreign correspondent Hugh Sykes usually reports from abroad, from Iraq, Turkey, Germany, Pakistan. But ahead of the general election on June 8th, he was given an interesting assignment - to visit three former industrial areas in the UK, to find out how they are changing and what undercurrents may be at play in the lead up to polling day. So here are his 'Election reflections' from Teesside, the former Yorkshire coalfields and South Wales.

John Sutherland was a high flier who joined the police in the early 1980s. At the height of his career he was appointed borough commander in Southwark in London, with its share of murders and violence. He was also a trained hostage negotiator. In 2013 he realised he could not cope anymore and has now written a memoir called Blue detailing his experience. He spoke to our reporter Becky Milligan. (Photo: John Sutherland.

She also meets Imogen's cousin Ashley, who is a long distance lorry driver, and will be voting Conservative.

It is 50 years since the law that decriminalised homosexuality was passed. John Browne, who was the chief executive of the energy company BP between 1995 and 2007, kept his sexuality secret for the first 50 years of his life. After being outed by the Daily Mail in 2007 he became the first person, leading a major publicly-traded company, to acknowledge that he is gay. But he later stepped down after revelations about his homosexual affair. In 2014 he published The Glass Closet: Why Coming Out Is Good Business. Lord Browne told Becky Milligan that in the business world it is tough to find role models, and if gay people come in to the sector and see no one like them at the top, they will go elsewhere.

It's been 50 years since the Sexual Offences Act 1967 was passed in England and Wales. The act was to amend the law and decriminalise homosexual acts in private between two men. In a time where public opinion of homosexuality was viewed negatively and MP's "were afraid of voting it in parliament for fear it would lose their seats,” David Owen supported the bill in a speech addressing the House of Commons on December 19th 1966. The former Labour MP tells our reporter Becky Milligan that as a society "we were in denial" regarding homosexuality and since amending the law society has "moved light years since the sixties".

To mark 50 years since the Sexual Offences Act in 1967 decriminalised private homosexual acts, Becky Milligan spoke to George Montague. Like many homosexual men of his generation, George got married, had children and kept his gay relationships secret. In 1974 he was convicted of gross indecency with a man - the law was repealed in 2004. The 93-year-old, who has fought for an apology for his conviction, finally received one from the Home Office.

Time to Change, a campaign run by the mental health group Mind, have published a survey which found that half young men in the UK would not feel comfortable speaking to their father about their mental health. When asked why, more than a third said it was because their fathers do not talk about their feelings and 31% said they would not want to burden them. The survey also revealed that over half of young men (54%) who are experiencing mental health problems 'put a brave face on' or 'keep it to themselves.' Richard has Contamination Obsessive Compulsive Disorder. Barry is his Dad. Becky Milligan talked to them about what they've been through.

Michael Gove gives his first interview on radio or television since his failed bid for the Tory leadership. He tells Martha Kearney about the mistakes he made in the days following the EU referendum, his thoughts on the government's education policy, his new review into preventing children in care from ending up in the criminal justice system and...whether he'd return to government.
