At this point, assertions such as these are a form of ad hominem fallacy against half of society. You are discrediting the multitude of sources who have covered this story because of the nature of the speaker while no hardline liberal outlets have covered this story at all and presented a counterargument. If you want to have an alternative narrative, you need to link a major outlet showing her to be a liar. The case has been presented to the public. You don't like the people presenting the case. That doesn't invalidate the case. You must, at this point, present a member of your team making a reasonable, evidenced based deconstruction of her claims. The fact that there isn't any coverage from your side at all of this incredibly well televised and written embarrassment for the legitimacy of crown prosecutors speaks volumes.

The UK is extremely litigious in regards to libel. Her lying would be an act of public libel against the crown prosecutor. She went on TV to talk about it. It's been well covered in everything from the IB Times to The Sun to the Daily Mail (as linked above), as well as fully televised on Piers Morgan. Naturally the team you obviously root for can just refuse to cover any prosecutions which are embarrassing for them and you can simply smugly say "well it's not in any source I personally recognize as valid so it didn't happen."
