The problem with this type of thing is intent.
How do we prove intent to deceive?
Lying is not simply stating incorrect information. It is intending to deceive by knowingly stating incorrect information. It is not easy to prove what someone knew.
What if they were misinformed by a third party that may or may not have an agenda? Under these circumstances the politician is not lying and believes they are telling the truth even though the information they uttered is wrong. Do you go after the third party? Does this then give the politician a mechanism to evade charges using fall guys?
I absolutely believe that people like Bojo should be held to account. In his case there was plenty of evidence. It should also be acceptable for the opposition to state that they were lying in the commons without facing repercussions.
I would have thought if Hunt is adamant there is no black hole that he would support the OBR in vindicating him. He only seeks to hide this because there must be a black hole. The only other explanation is that the OBR has taken sides against him, but that would seem unlikely in such a short time since Labour took office. More likely the conservatives were suppressing the OBR when in office.
P.s. Isn’t that the OBR’s job anyway?
