I prefer the short documentary style series rather than any 'ongoing' on-the-fly "radio" talk show type things. Some interesting ones over the last few years (most tend to be US but some UK):
Where is George Gibney?
The Last Days of August
Chameleon (first series anyway)
Cautionary Tales
The Drop Out: newsworthy right now with the trial of Elizabeth Holmes underway
Slow Burn - Watergate
Slow Burn - Bill Clinton's impeachment
Slow Burn - David Duke
Catch and Kill (about Harvey Weinstein)
Serial
S-Town
Nice White Parents
And selected episodes/story arcs from This American Life, The Guardian Today in Focus
