Tom Little KC may have worked at the Treasury but I don't reckon he's doing that well. First he says the precise date of birth is known only to the defendants and then he reads an interview transcript in which CM says Victoria was born on Christmas Eve. If she chooses to go into the witness box, it's possible the prosecution will challenge her and put it to her that she has a tendency to make stuff up, or to forget stuff and then to swear blind that what really happened was whatever she's imagining on the spur of the moment, and that therefore nothing she says about anything is worth giving credence to unless it's corroborated. But it's also possible they won't contest the birthdate, in which case he may be thought to have been going super over the top today. There was "as if she was refuse" too.
Similarly if Victoria was born on 24 December and the couple left the accommodation on 26 December, some uncleared-up "food remnants" left behind might not be much of a surprise.
The fact that the placenta was in the Peugeot 206 on 5 January, though? When did they buy that car? Why keep a placenta? Or maybe she gave birth in the car even while they were staying in the accommodation.
Do the grounds for three of the five charges (manslaughter, cruelty, and causing or allowing death) perhaps depend on the idea that since they were on the run (not being wanted for any offence), they were avoiding the SS whom they knew would take their child, and it was cold, it must have been criminal negligence on their part that caused Victoria's death? If that's so, the charges may not even survive half-time because the judge may well take a "where on earth is the evidence?" view.
The perversion of course of justice charge might also fall at that point. I'm not sure what they are supposed to have done that did pervert the course of justice. After all, they didn't burn or otherwise dispose of their daughter's body.
Probably one of the three charges mentioned above would have to be proved for PotCoJ also to be proved.
