This 12 point reduction story is complete and utter codswallop started by a very unreliable tabloid and then copied, repeated and regurgitated. Simple common sense tells you that it would be illegal for the PL to interfere/influence an ongoing 'independent' investigation and doing so would leave them open for legal action. Even if they had been idiotic enough to do that, they definitely would not be telling news media about it.
Unless a story comes from someone very reliable, take it with a pinch of salt and use discernment with everything.
….would you expect the PL to come out and refute it?
