Sacked FBI Chief to Testify Before Congress

There's anticipation in Washington, where the sacked FBI director James Comey is preparing to testify about his dealings with President Trump. In a document released ahead of the congressional hearing, Mr Comey says Mr Trump asked him to let go of the investigation into contacts between Mike Flynn, the former national security advisor, and Russia.

Also on the programme: An exclusive report about life under the Taliban in Afghanistan's Helmand province; and the 26-carat diamond bought at a car boot sale.
