Today is the turn of sub-postmasters’ representatives to ask questions of Vennells – and they are unlikely to hold back.

The inquiry room is buzzing – it’s busier than I’ve ever seen it – and there’s not a spare seat to be found.

I’ve already spotted several sub-postmasters here, including Lee Castleton and Seema Misra, and there are many others in the room.

As a quick reminder, more than 900 sub-postmasters were wrongly prosecuted between 1999 and 2015 due to faulty accountancy software called Horizon, which showed errors that did not exist.
