Marriott hotels say a cyber attacker has accessed data for up to 500 million customers. The online security expert Graham Cluley tells us what's known about the data breach. Also in the programme, with leaders of the G20 group of countries gathered in Buenos Aires, Argentina, trade is at the top of the agenda. Our correspondent discusses the deal that has been signed between the US, Canada and Mexico, and tells us whether any progress is likely on the dispute between the US and China. We're in Brussels, looking at how Brexit is expected to shape the future of the European Union. We also have a report from Andalucia in southern Spain, examining how this weekend's elections are likely to affect the region's economy. Plus we look back at the rest of the week's big business stories, with Charlie Wells of The Economist in London, and Melodie Hahm of Yahoo Finance in New York.
