BBC Panorama 'used LSE students as shield' for N Korea film

The London School of Economics (LSE) and its students' union have demanded the BBC withdraw Monday's Panorama programme about North Korea.

The LSE said Panorama reporter John Sweeney posed as one of its professors on a university society trip in order to film undercover in the country.

The union's Alex Peters-Day said the BBC used students "as a human shield".

Sweeney said the students were told a journalist was with them but that the LSE was not, as it was not an LSE trip.
