We look at the outsized influence of a small and secretive Catholic institution, Opus Dei, from Spain's dictator Franco to Trump. And the bank it controlled for sixty years. Plus: in the latest twist in the epic battle to end anonymous ownership in the United States, the US's financial regulator FinCEN has announced plans to actually delete company ownership information. We look at the options to stop the US sliding even further into a corruption abyss.

The persecution of anyone suspected of being an undocumented immigrant in the United States is not only taking the form of armed, masked ICE agents. Tax is being weaponised against them too. An estimated 10.9 million undocumented immigrants are the powerhouse of the United States economy, and also an exploitable workforce with minimal rights. It turns out that they're paying a higher effective tax rate than 55 mega-corporations and several billionaires. We look at the data that show how devastating it is for the economy and public services too. Plus: bullying at home, bullying abroad: President Trump is deploying tariffs and threats of tariffs against countries who have the audacity to want to tax US multinationals fairly.

It's also time for Ireland to rethink its tax haven model and for many countries, not just Ireland, to ask who it's economy is serving.

The Taxcast looks at the battle for freedom of the press in Switzerland and the implications for the rest of the world. Investigative journalists like Bastian Obermayer risks arrest, fines and imprisonment if he sets foot in Switzerland again, and Swiss journalists are having to turn away strong public interest stories - for fear of not just rich and powerful people coming after them, but also the Swiss state. Switzerland's always been famous for its banking secrecy laws and it's never been the friendliest place for investigative journalists. Now the situation threatens to get even worse.

How easy is it to get filthy rich selling arms to anyone who'll pay? There may be sanctions, there may be laws, but even though he's the FBI's most wanted fugitive, a Chinese arms dealer and manufacturer has evaded arrest for two decades.
