Stephen Hawking to deliver BBC Reith lecture on black holes

Radio 4 announces new autumn lineup as Glenda Jackson returns for drama series and Miles Jupp takes over as presenter of News Quiz

Professor Stephen Hawking is to discuss the nature of black holes, and former MP Glenda Jackson is to return to acting in a Radio 4 autumn schedule announced on Tuesday.

Hawking will deliver the prestigious Reith lecture later this year to "describe the remarkable properties of black holes" and will answer a selection of questions submitted by listeners. The lecture coincides with the BBC plans for a series of events to mark 100 years of Albert Einstein's theory of relativity.
