I’m a bit late with this, but BBC Radio 4 Extra are broadcasting a few Big Finish 6th Doctor stories atm, starting two weeks ago with ‘The Crimes of Thomas Brewster’, followed by Ep1 of Industrial Evolution last Saturday, Ep2 next Saturday & Ep1 of The Curse of Davros on the 25th. I don’t know if there are anymore after that, because the BBC don’t release schedule information that far ahead.

Episode 1 of The Crimes of Thomas Brewster is available on the iplayer for 14 days, Episode 2 for 21 days, Episode 1 of Industrial Evolution for 28 days & BBC radio normally works outside the UK.
