If Ashcroft were to make these allegations in a court of law, not an autobiography, he would asked some searching questions, such as -
1) "Did you observe this in person?"
If the answer is "no" then the testimony is hearsay, and not admissable, and the next Q is
2)"Who told you this?" so that the information can be traced back to its source.
If the answer to Q1 is "yes", then the next questions are -
3) "Were you a member of the same initiation ceremony?" because if so, then he would presumably have gone through the same initiation himself - which tars him with the same brush. Pots and kettles.
4) "Who else was present?" so that corroboration can be sought.
5) "Why did you wait all those years to disclose this about a man who aspired to high office?" Was it perhaps, because Ashcroft thought he could use it to blackmail himself into office and then turned on Cameron when that preferment failed to materialise? Blackmail is an offence.
Than there are other questions. He claims it was an initiation rite of the Bullingdon club. Someone else has said that JC was never a member of that club. Inconsistency.
Somehow, I can't help feeling that this has no substance, and that is not because I see JC wearing a halo of sanctity and perfection. Heaven knows how let down Corbyn's fervent supporters will be if someone produces a similar accusation against him and their holy image of him. But they would of course have to prove chapter and verse.
