The latest bleatings on Boris the Liar are along the lines that he is innocent because nobody told him what they were doing was wrong - and since nobody told him it was wrong then he can't have misled parliament.
He seems to have missed the bit about taking personal responsibility and knowing what the regs were at the time, just like the rest of us had to, especially since he was responsible for those regs that applied to where Downing Street is located.
