Qatar's Emir will discuss economy and security with Donald Trump

Qatar’s leader, Emir Sheikh Tamim bin Hamad Al Thani, will discuss the economic blockade of his country, by nations in the region led by Saudi Arabia and Gulf security, when he meets Donald Trump at the White House on Tuesday.The meeting comes as the United States grows concerned about attacks on oil tankers, which Washington blames on Iran. Ellen R. Wald, an expert on Qatar's energy driven economy, explains why the country could seek the help of the US to deal with the sanctions imposed by Saudi Arabia, as well as give President Trump an inside track on Iran's nuclear policies.

Ireland and the UK are at loggerheads over a British territorial claim to Rockall, a small outcrop in the North Atlantic. The BBC's Russell Padmore explains how Brexit could make the decades long dispute worse and how Irish fishermen have refused to stop casting their nets around Rockall, which they claim is part of the European Union.

Also in the programme, the latest evidence shows the pace of deforestation in the Amazon rainforest is accelerating, as a new government in Brazil favours economic development over conservation.
