BBC denies claim that students were put at risk

The BBC has denied claims that it put students from a London university at risk when an undercover journalist accompanied them on a field trip to North Korea.John Sweeney, a reporter for the Panorama programme, is said to have joined the student group from the London School of Economics (LSE).

He joined them on a visit to the communist country to carry out secret filming.

The LSE says the students "were not given enough information to enable informed consent", and were "endangered", the BBC reported.

The LSE's director, Professor Craig Calhoun, accused the corporation of "lies and deception from the outset".

He told Sky News the BBC was "unwilling to take responsibility" for the risks it caused to students.

The BBC denied giving students insufficient information about plans for secret reporting.
