Last month we brought you news of BBC Radio 2’s exclusive 60-minute interview, Who on Who?, between David Tennant and Russell T Davies, who both bid farewell to Doctor Who as the Tenth Doctor and showrunner with the transmission of The End of Time, Part Two on New Year’s Day.

The programme aired earlier today, and is now available to listen to again for the next 7 days on the BBC’s iPlayer service.

In the chat, Tennant questions Davies about everything Doctor Who, including his thoughts on its new showrunner, Steven Moffat, whether or not he would ever consider writing for the programme again, and how he originally declined the BBC’s offer to produce a series based around a young Doctor studying at the Time Lord Academy.

Their final episode will screen in the UK this Friday at 6:40PM on BBC One/HD.
