Former CNN broadcaster Larry King has spoken to the BBC about what he has learned about interviewing, after 58 years in the job.

The 81-year-old stepped aside from his role with the cable news station after 25 years but is still making programmes, including for a news channel backed by the Russian state, RT.

Speaking to Newsnight's Evan Davis, the veteran journalist also addressed his spat with his successor at CNN, Piers Morgan.
