If you break it down, it is a litany of mistakes and offences for which he offered no regret or apology.
1) 27th March - rushed home, Mary was ill but then went back into work.
2) When did he fill up the car for the trip north on 27th?
4) Would they normally travel 4 hours without a toilet break & how did their son cope with that journey?
5) He wrote about coronavirus last year and the need for planning
6) Why was it safer to return to work and leave wife and son in house on 13th April compared to 27th March
Had he sorted security?
8) Why go to Barnard Castle? Was this really a trip for Mary's birthday?
9) If once he got there and started to feel sick, should Mary have drove back?
12) Were questions 7-11 all breaking the stay at home message?
Exercise 1 x a day, shop essentials
14) Where did he stop on the return journey from Durham?
15) Why didnt Mary drive or share the driving?
It does appear to show one rule for Cummings and a different one for us all.
His defence was safety in London. Yet still broke rules in Durham.
You have to now question not just Dominic Cummings but also Boris Johnson for believing this was acceptable.
