Who finances the Sudanese regime?

Thousands of people have marched across cities in Sudan to condemn the killing of protesters, as the country's ruling generals and the opposition say they will resume talks to form a new transitional government. The demonstrators on Thursday were heeding a call for a "million-man march" to protest the killing of four school children at a rally earlier this week. We look into the financing behind the regime the protesters are trying to overthrow.

With just 91 days til the UK is due to leave the EU, we ask how prepared businesses are. Alistair MacMillan set up White House Products which sells hydraulic pumps to 120 countries, voted for Brexit, and is fairly relaxed about the prospects for trade. Helen Roberts of the National Sheep Association in Wales discusses the impact tariffs on lamb could have on exporters. And we examine the costs and benefits of Brexit with Roger Bootle of Capital Economics, and Jonathan Portes, who runs UK in a Changing Europe.

Also in the programme, as the 50th anniversary edition of the Woodstock Music Festival scheduled for later this month is cancelled by promoters, we ask Paul Reed of the Association of Independent Festivals in the UK whether the festival business model is broken.
