In April 2022, two months after Russia invaded Ukraine, a man in his thirties called Victor Muller Ferreira flew into Amsterdam airport using a Brazilian passport. He was identified by the Dutch authorities as Russian national Sergey Vladimirovich Cherkasov and immediately sent back to Brazil, where investigations by both the FBI and the Brazilian police identified him as a Russian intelligence officer. He had been living in Brazil, undercover, for years, with a well-developed personal 'legend', or cover story, that included a passion for Forró, a popular Brazilian partner-dance. Cherkasov is currently serving a five year prison sentence in Brazil for identity fraud, and Russia demands his extradition.

Leandro Prazeres of BBC News Brazil - who happens to be a big fan of Forró himself - and BBC Russian's Olga Ivshina unpack the story of this 'fake Brazilian' and explore the history and motivations of Russia's network of so-called 'illegals', or deep cover spies.

This episode of The Documentary comes to you from The Fifth Floor, the show at the heart of global storytelling, with BBC journalists from all around the world.

Produced by Laura Thomas, Caroline Ferguson and Hannah Dean.

Albania: Land, money and the sea

Albania has had many different faces over the last hundred years. Once ruled by the Ottomans, it became a kingdom before turning into a totalitarian communist state after the Second World War. During this time, no one was allowed in or out; all private property became state-owned, and bunkers sprang up across the country. After the fall of the communist regime, Albania descended into chaos. In 1996, a pyramid scheme that three quarters of the population had paid into, collapsed. People lost everything, and the country, especially the south, erupted into violence.

These days, Albania is aiming to shake off its past and transform its reputation from a country marked by corruption to one known for luxury tourism. With its miles of unspoilt beaches, snow capped mountains, and olive groves that could rival anything Greece has to offer, it’s unsurprising that it’s quickly attracting investors. Among them are Ivanka Trump and her husband, Jared Kushner, who are hoping to build a resort on an island off the coast of Vlorë. They have visited the secluded beaches of Zvërnec and Nartë; currently home only to endangered monk seals, sea turtles, and a few sheep. They, like others, hope to benefit from new government incentives to build luxury 5 star plus resorts.

However, ghosts of Albania’s communist past remain. Land disputes, allegations of corruption, and a lack of infrastructure could derail these resorts before they’ve even broken ground. For Assignment, Emily Wither travels to Albania to find out whether it will be able to re-brand itself, and whether its dream of luxury escapism will become a reality.

This episode of The Documentary comes to you from Assignment, investigations and journeys into the heart of global events.
