Theresa May, the former Tory leader, says the public "had the right to expect their Prime Minister" to "set an example in following those rules".
"What the Gray report does show is that 10 Downing Street was not observing the regulations they had imposed on members of the public.
"So either my Right Honourable friend had not read the rules, or didn't understand what they meant or others around, or they didn't think the rules applied to them. Which was it?"
Boris Johnson insists "that is not what the Gray report says", and suggests that she "waits to see the conclusions of the inquiry".
