Signed, Sealed, Delivered

Everyone is talking about letters of no confidence this week so Matt looks through letters which have shaped politics down the years, from campaigns to get prime ministers to change their policies, to Harold Wilson's letter to Daniel Finkelstein about watching the muppets. Daniel Finklestein, Dr Kit Kowol and Professor Richard Toye speak what we can learn from political letters.

PLUS FORMEL: James Forsyth and Melanie Reid on the political tv drama we're in and train announcements.
