The PM Glass Box. Happy 80th birthday to Katie Boyle.
The Glass Box is where the PM team meets in at 18.00 every weeknight to discuss the content of the programme.
We try to be honest with each other, but not hurtful, as we talk about what worked and what didn't...what met our expectations and what fell short.
This virtual glass box is where you're encouraged to take part in the same spirit. Tonight's PM editor Briony Harris will read your comments and may well add her own.
